Cost vows to help Falcao back to his best.

Jose Mourinho says that Costa is a man who can't speak English but communicates better than anyone. 

He has a fighter's face which can break into a smile or a scowl.

Last season, his 20 goals in 26 Premier League matches elevated Chelsea to champions. He also seemed to be the man most likely to be at the centre of an argument. 

From day one, defenders seemed to mark him down as a man they had to fight as much as play. Costa (right) seemed to relish the contest.

Does he like the aggression? 'No,' he insists. 'I like to play football, I like to score goals, I like to do things well.

'You can get different games, some which are more of a battle, some which are less hard-fought.

'Goals are what count for me. 'Fighting hard, giving everything and working hard has to be combined with the goals. It doesn't matter if defenders want to battle me or not, I will just be trying to do my job as well as I can.'

Alongside him will be an old friend. Radamel Falcao was the star at Atletico Madrid when Costa was the understudy, before the Colombian's £52million move to Monaco which went sour when he ruptured knee ligaments.

Since then there has been the misfiring attempt to restore his reputation at Manchester United. 

Now they are reunited but with roles reversed. Costa, now the leading man, is pleased it didn't work out at United.

'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 team-mates and he will help us a lot off the field too.'

The ruptured knee ligaments were not the reason for Falcao's form last season, according to Costa.  Indeed, a little tenderness should restore him to the Falcao of Atletico. 

'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.'
