Diego Costa has admitted that he is "very excited" to be working with Radamel Falcao at Chelsea this season.
The strikers were teammates at Atletico Madrid before the Colombian, who is at Stamford Bridge on a season-long loan, moved to AS Monaco in 2013.
The Spanish international told the Daily Mail: "It's good for us that he didn't have the best of seasons as that's why he's now with us. We know that Falcao is a hugely talented player. The only thing he needs is to feel loved and trusted, and he will get both here.
"The manager is very happy to have brought him in and we are all very excited to have him in our squad because he's a great player. He gets on very well with his teammates and he will help us a lot off the field too.
"I suffered an injury similar to his and now I'm fine. All he needs is the consistency of regular football and to feel loved. If he wasn't very happy at United, whatever may have been missing there, he will get it here."
Falcao spent last season on loan with Manchester United, but Louis van Gaal's side turned down the chance to sign the striker on a permanent basis.
