Manchester City

Manchester police and the Football Association have urged fans of both Manchester teams to show restraint ahead of tonight's final leg in the Carling Cup semi-final.

Sir Alex Ferguson and Roberto Mancini have been told to remind their players of their social responsibilities as the two clubs face each other at Old Trafford. The first leg was blighted by incidents on and off the pitch, with the arrest of 18 Manchester United and Manchester City supporters.

Brazilian striker Robinho has been questioned over an alleged sexual assault in Leeds. The Manchester City star, 25, denies the allegations.

Robinho cost City a British record £32.5 million when he signed from Real Madrid this summer. Despite performing well on the pitch, scoring 12 goals, he has recently been embroiled in controversy.

This week the Brazilian International was fined after he left the club's training ground without permission. The striker said he had to attend to a family matter and said he believed he did have permission from the club.
