REAL MADRID star Toni Kroos warned Manchester United players that their new team-mate Casemiro will push them to their limits in training.
The Brazilian midfielder put pen to paper on a four-year deal, with the option of an extra year, following a £70million deal between United and Real.
Kroos and the 30-year-old enjoyed a stunning partnership in the middle of the park alongside Luka Modric in the last seven years and together they won five Champions League trophies.
All that success brought the two stars together and the Germany international issued a farewell letter to Casemiro, which was published by Marca.
The 32-year-old looked back at all the times the Brazil international kept him on his toes.
And the German warned Cristiano Ronaldo and co that Casemiro will put them through their paces as he always demands perfect physical condition from his team-mates.

In fact, the ex-Bayern Munich star informed his new United team-mates that he will only let them lie down to do sit-ups.
Kroos wrote: “With you, my dear Case, it was impossible not to break a sweat… in any situation.
“Because you wouldn’t let us relax even in the Turkish bath. Meeting there was another torment: you told someone to go and you almost had exercise bikes and weights ready.
“A warning for your new colleagues to know. Because with you even the Turkish bath was a gym… and you only allow people to lie down when it’s time to do sit-ups.
