Manuel Pellegrini insists his Manchester City squad has enough depth to cope with challenging for two major competitions despite a difficult start to an important week.

Pellegrini's team heads to the Czech Republic to face Viktoria Plzen in the Champions League on Tuesday - a competition that has seen City fail to get out of the group stages in its previous two campaigns.

After that it hosts Manchester United at Eastlands in the first Manchester derby of the Premier League season.
