Manchester City have been warned that they will be facing a striker every bit as good as Neymar and Luis Suarez in Zlatan Ibrahimovic at the weekend.
The former Sweden international, who will be 35 next month, has made a good start to his Manchester United career with three goals in as many Premier League matches since arriving on a free transfer from Paris Saint-Germain in the summer.
He will take part in his biggest game yet for the Reds at lunchtime on Saturday when Jose Mourinho's side host Pep Guardiola's City in the derby.
Both sides have a 100 per cent record so far this season and something has to give at Old Trafford, where City will be without their own star striker Sergio Aguero through suspension.
