Diego Costa is glad Radamel Falcao flopped at Manchester United so Chelsea could snap him up.
The Colombian has moved to Stamford Bridge on a season-long loan deal despite scoring just four Premier League goals during a similar spell with Manchester United last term.
Mourinho revealed that the striker took a pay cut in order to prove wrong his critics in England and his former Atletico Madrid team-mate is confident a better atmosphere will see Falcao shine again.
"It's good for us that he didn't have the best of seasons as that's why he's now with us," he is quoted as saying by the Daily Mail.
"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 team-mates and he will help us a lot off the field too."
