$ 0 0 ManchesterCity swept into the League Cup final with a ruthless 3-0 win at West Ham on Tuesday which completed a 9-0 aggregate victory in a brutally one-sided semifinal. Manuel Pellegrini's side had already effectively booked their place at Wembley after winning the first leg 6-0 at Eastlands, but they didn't take it easy in the return at Upton Park. Alvaro Negredo and Sergio Aguero put City two goals up before half-time in east London and Negredo struck again after the break to cap another clinical display from one of the most potent strike-forces in Europe.City will face arch rivals Manchester United in the final on March 2 if David Moyes' side can overturn a 2-1 deficit in the second leg of their semi-final at Old Trafford on Wednesday. With City in possession of a seemingly unassailable advantage, Pellegrini made eight changes from the side that beat Cardiff in the Premier League on Saturday.
