Chelsea boss Jose Mourinho: 'Diego Costa will thrive without pressure now'

Chelsea boss Jose Mourinho has tipped Diego Costa to rediscover his form of last season after ending his goal-drought in Saturday's 1-0 win over Norwich City at Stamford Bridge.

The 26-year-old hitman struck the winner on 64 minutes for what was his third Premier League goal of the season and first for seven games.

Costa netted 20 times in the league last term to help the Blues cruise to the title, and Mourinho is hopeful that the floodgates will now open for his marksman once more.

"With so many pundits in the papers, on the television and on the radio, some of them are strikers and know the feeling," he told reporters.

"You don't score goals, you get heavier. Every game that you don't score goals, you have five kilos more. You get heavy and the pressure is there. First half he misses two chances - the second one in the last minute is really a big one - so it was important for him [to score], important for us.

"He's working well, he's a happy guy. He tries everything, he's positive. If I had to choose somebody to score the winning goal, I would go exactly with him."

The champions sit 15th in the table.
