Inter Milan boss Jose Mourinho has hit back at England manager Fabio Capello, saying he knows nothing about football.

After Capello said that Inter 'had' to win this season's Champions League, Mourinho came out and responded to the comments, saying it would be hard for any team to just come out and win in Europe.

Although he did not directly use Capello's name, it was clear to see where Mourinho was headed with retort.

"In this Champions League, there are a lot of teams who have already got a settled team like Barcelona, Chelsea, Manchester United and Arsenal," Mourinho said.

"Then there is Inter, who have a big squad but the team is still under construction. It is like this for Real Madrid and Bayern Munich.

"Last season, none of the Italian teams did well but I don't think that this year it will go as badly.

"But whoever says that Inter 'have' to win the Champions League knows nothing about football, and in the place of 'nothing' I could use much stronger words."
