Manchester City beat League Cup holders Liverpool 3-2 in a cracking game on Thursday, taking the lead three times before holding on to reach the quarter-finals.
Chelsea paid a heavy price for a 3-2 defeat at West Ham United as first Liverpool, then Manchester City, leapfrogged them in the English Premier League title race on Saturday, with City ending the day on top for the first time this season.
Arsenal manager Arsene Wenger said he is still keen to sign Uruguayan striker Luis Suarez even though Liverpool have rejected two offers from the Gunners for him.
However, one goal proved enough for City who picked up their sixth successive league win to move four points clear of Liverpool, who host Aston Villa later on Saturday, at the top of the standings.

Juergen Klopp's reign as Liverpool manager began with a few points made but only one gained from an exciting, end-to-end 0-0 draw against Tottenham Hotspur at White Hart Lane on Saturday.
