Middlesbrough 1-0 Chelsea – Carabao Cup semi-final LIVE RESULT: Hackney fires Boro to iconic win at Riverside

That’s all from the Riverside

But, thankfully for Chelsea, it’s not the end of the tie.

The Blues will have to be much better in the second leg at Stamford Bridge in two weeks if they are to overturn this one-goal deficit – and they will need to learn how to put the ball in the back of the net.

Depleted Middlesbrough were excellent throughout, soaking up large spells of pressure and then punishing their Premier League visitors on the counter.

Michael Carrick’s men are more than in this semi-final at the halfway stage, and can head into the return fixture full of belief with Wembley just 90 minutes away.

Thanks for joining us, and goodnight.

Poch: We made mistakes

Chelsea boss Mauricio Pochettino insisted his side’s approach was the right one tonight, but they were simply punished by some mistakes at either end of the pitch.

The Argentine remains confident that his team will turn around the deficit during the second leg on home soil.

The approach was good. I think we made some mistakes. I think we gave them chances to score, and then they were really tough. They played in transition with a low block. Still, we had many chances to score but we didn’t. We have another 90 minutes at Stamford Bridge and we need to be positive.

Sterling struggles with another semi

Some of the fiercest Chelsea criticism this evening is being directed at Raheem Sterling, who struggled to make an impact against Championship opposition.

By failing to find the net, it means that the forward’s run without scoring in a semi-final extends to 21 such matches.

Harsh throwback for upset Blues

It’s been a quarter of a century since Chelsea last lost a League Cup game inside 90 minutes to a lower division side.

In other words, it was pre-Abramovich.

Match stats from the Riverside

Defeat for Chelsea who had 18 shots, 72% possession and what felt like 250 crosses that went straight out of play.

Full time – Middlesbrough 1-0 Chelsea

Advantage Middlesbrough!

Hayden Hackney’s first half goal means that the Championship club will take a 1-0 lead to London for the second leg in a fortnight.

Chelsea huffed, Chelsea puffed, but did so little that their lower-level hosts were comfortable.

It’s a point not lost on the travelling fans either. As the home fans celebrate, the visiting section are letting their players know exactly what they think.

Thiago Silva heads over in an attempt to appease the booing Blues, but something seems seriously amiss with the Stamford Bridge club.

Middlesbrough 1-0 Chelsea

90+4. A final chance of the evening is headed into the side netting by substitute Alfie Gilchrist.

It took a nick so leads to a corner, but Fry, Clark and Engel are up to the task, just as they have been all evening.

Middlesbrough 1-0 Chelsea – Jones yellow card

90+2. Middlesbrough’s Isiah Jones is cautioned for time wasting over a throw-in on the near side.

If we’re truly talking time wasting, then the whole Chelsea squad should go into the book.

90. There’s a few seconds respite for Middlesbrough as Matt Crooks receives treatment after rolling his ankle.

It’s the cue for the fourth official to hold up the board that shows there will be four minutes of additional time.

The Riverside Stadium is as loud as it’s been tonight.

Middlesbrough 1-0 Chelsea

88. The Middlesbrough defence are standing tall to everything that’s been thrown at them.

A Clark header out. A Fry volley clear. Clark again when Chelsea return with another centre.

86. We have a late new entry for worst cross of the evening, and it’s straight in at number one.

Stand up, Conor Gallagher.

Middlesbrough 1-0 Chelsea

85. Five minutes remain on the night, 95 to go in the tie.

Middlesbrough lead by a single goal, and it’s all getting a little frantic as they try to protect it.

It’s a sea of red bodies as Gallagher lines up an effort, one that is bravely blocked at close quarters.

83. A Chelsea corner leads to some pinball inside the Middlesbrough six-yard box but before anyone in blue can pounce, Jonny Howson emerges to thump to safety.

A captain’s contribution.

Middlesbrough 1-0 Chelsea

81. And it almost does!

Broja comes left to finally involve himself, and then offers a directness that has been lacking from Chelsea tonight.

The Albanian cuts back inside and then out again before sending a cross-shot towards the far post.

It evades the outstretched arm of Glover – but also the outstretched leg of Sterling.

Middlesbrough 1-0 Chelsea

79. Armando Broja has only touched the ball five times since coming on – and still looks a bigger threat than Mudryk.

If only Chelsea could get the ball to him, then something may happen.

77. The home fans raise the noise levels for one last push.

The Middlesbrough supporters have put in as big a shift as their players tonight.

Middlesbrough 1-0 Chelsea

75. Chelsea have had 75% of possession in the second half, but only recorded five attempts at goal.

Thanks heavens the transfer window is open, and Todd Boehly can put all this right…

Middlesbrough 1-0 Chelsea

73. Since he came on 13 minutes ago, Mudryk has specialised in dribbling the ball straight into opponents.

71. You know things are bad when even Thiago Silva is making mistakes.

The Brazilian legend slips over on the wet surface as Boro launch their latest counter, and it momentarily lets Coburn through on goal.

The youngster doesn’t have the pace to outstrip the 39-year-old, however, and Silva soon gets back to push him off the ball.

There was the option for Coburn to slip in Crooks, but opted against it thinking his teammate was offside.

70. Bizarrely, that double Chelsea change seems to have spurred a new lease of life into Middlesbrough.

The Blues look even more toothless than they did before.

Middlesbrough 1-0 Chelsea

68. For a side that has spent so much of the second half defending, Middlesbrough love to get numbers forward when the opportunity presents itself.

A corner follows that last counter, and shortly afterwards Barlaser takes aim with a rising blaster from 25 yards out. Over.

Middlesbrough 1-0 Chelsea 

66. No, Boro still have the will and ability to attack!

Coburn does very well to hold up play, and then brings in Crooks, who releases Jones.

The winger drives into the penalty area and goes searching for former Rangers man Crooks at the far post.

However, this time Jones gets his delivery wrong, sending the low centre behind his teammate.

Middlesbrough 1-0 Chelsea

65. Middlesbrough have dropped very, very deep.

As Chelsea probe forward again, the hosts have nine players back inside their own penalty area.

Are they happy to protect their one-goal lead?

Middlesbrough 1-0 Chelsea – Chelsea double substitution

63. Here we go!

The electronic board goes up and it’s the end of the night for Enzo Fernandez and Noni Madueke.

Mauricio Pochettino has sent for Mykhailo Mudryk and Armando Broja.

“What a waste of money!” rings around the Riverside Stadium. Take your pick at who that’s aimed at.

Middlesbrough 1-0 Chelsea

61. Gallagher works a half-chance for himself, controlling a cross from right and acrobatically spinning in one movement while falling backwards.

Mid-breakdance, the Chelsea captain gets a shot away that veers wide of the far post.
