Manchester United are on the verge of making a signing that could transform their team. For years, Manchester City preyed on the weaknesses of United goalkeeper David de Gea as they pressed aggressively knowing how uncomfortable he was with the ball at his feet.
When they last met in the FA Cup Final in June, even the Spaniard's biggest strength of shot-stopping had deserted him as Ilkay Gundogan scored two volleys from outside the box to tee up the Treble.
Andre Onana was in goal to see Pep Guardiola's side win their third trophy of a memorable campaign and will now be seeing a lot more of them as he nears a big-money move from Milan to Manchester.
United could be a different team with a very different goalkeeper between the sticks. However, any Reds getting too far ahead of themselves - or Blues moaning about a lack of action in the transfer window so far - should remember both clubs have been here before very recently.
