Mourinho is desperate to compete with the Premier League’s big four in the Champions League next season.
“We have just won Serie A with Inter but I know United are better than us,” Mourinho wrote in his column in The Sunday Telegraph.
“We were very close to beating them, so if we improve we will be close, very close to the teams from The Premier League.
“But it is very difficult to get players.
“One player who would improve us at Inter is Ricardo Carvalho.
“He is not playing at Chelsea now and it looks like Alex is in front of him, so maybe it is better to let him come here and play.”
