Manchester City have been warned they may ultimately fold under the huge pressure of chasing an historic treble.
Pep Guardiola's side remain on course to match local rivals Manchester United by winning the Premier League, Champions League and FA Cup in the same season. City took a step closer to that Holy Grail with a battling 1-1 draw at Real Madrid in the first leg of their Champions League semi-final on Tuesday.
A majestic second-half strike from Kevin De Bruyne salvaged a draw for Guardiola's men and has given them every chance of making the final in next week's return leg at the Etihad Stadium. But with Arsenal refusing to go away in the title race, Guardiola will have little option to rest key players for Sunday's trip to Everton, three days before the decisive return leg against Real.
