Manchester City boss Roberto Mancini concedes David Silva is struggling for form.

The Spaniard was City's most influential player for much of last season but, like several of his team-mates, he has struggled to find the same form this campaign.

"It is difficult for him," said the City boss. "He's human and probably he's not 100%. I don't think he needs a rest but he played the European Championships and afterwards he travelled twice away, once to Puerto Rico, so for this reason he could be not fresh."
