Manchester City coach Pep Guardiola has said his side were back to their old selves following a 6-0 demolition of Ipswich Town on Sunday that moved them into the Premier League top four. City put their struggles over the last two months behind them as Phil Foden scored twice and set up another goal and Erling Haaland also got on the scoresheet in a much-needed win that moved them up to fourth on 38 points.
