My combined XI, from Manchester United's 1999 Treble winners and the Manchester City team looking to emulate them over the next three weeks, would be a 4-3-3 shape.
Yes, it's weighted 8-3 in favour of Sir Alex Ferguson's United, because they set the bar 24 years ago and their achievement hasn't been matched by Pep Guardiola's men... yet.
Of the current City contingent, only Ruben Dias, Kevin de Bruyne and Erling Haaland get the nod. That sees Peter Schmeichel keeping Ederson out between the sticks, with Gary Neville, Jaap Stam and Denis Irwin joining Dias in the back four.
