Former Arsenal manager Arsene Wenger hit out at Manchester United's failure to deal with Manchester City in the wide areas following their 6-3 humbling at the Etihad Stadium on Sunday afternoon.
United, who arrived at the Etihad on a run of four consecutive Premier League wins, were blown away by their cross-city rivals, finding themselves 4-0 down by half time.
City made it clear that they were going to try and target United's right-flank as a weakness, highlighted by Diogo Dalot being yellow carded inside the opening two minutes after bringing down Grealish. City also threatened down the right, with Phil Foden giving Tyrell Malacia the run-around.
