Aitor Karanka says he has been delighted with Tomas Kalas' contribution since joining on loan from Chelsea in the January transfer window.





Kalas could play his last game for Boro at Carrow Road on Friday before his loan deal expires, and the Head Coach is pleased that all three parties have been satisfied with the deal.





"I'm very, very pleased (with Tomas)," said Karanka.





"The main thing is that the three parties are pleased. Chelsea are happy because he didn't play before coming here and we are happy because he's played and contributed a lot with his performances.





"It's also good for him. He's happy because he's played games and when you're 21-years-old you need to play.





"He's played here, re-discovered his confidence and I think it's been another good loan for everybody."





Another Chelsea loanee who has impressed during his time with Boro this season is Patrick Bamford.









"Patrick has improved a lot," he said. "He joined an amazing team here who have helped him a lot to play at his best, but it's true he's had an amazing season.





"He's scoring, playing as a striker and as a winger. His performances are always brilliant and I don't have any doubt that he's the best young player in the league."
