Pep Guardiola tore into Leroy Sané during a furious dressing down at half-time of Manchester City’s shock FA Cup defeat by Wigan Athletic last week.

Telegraph Sport has learnt that Sané’s team-mates were left stunned as Guardiola accused the Germany winger of failing to pull his weight and not adhering to his specific instructions in the first half of the 1-0 defeat.

The manager was so angry he substituted Sané at half-time and brought on right-back Kyle Walker. Guardiola was already irate before he entered the dressing room after confrontations on the pitch and then in the tunnel with Wigan coach Paul Cook following City defender Fabian Delph’s red card in the final minute of the first period.

Guardiola’s mood darkened further when he turned on Sané, with one source claiming the Catalan’s dismay with the 22-year-old could even be heard in the corridor outside the dressing room.

Sané was back in the starting XI for the Carabao Cup final triumph over Arsenal at Wembley on Sunday. Guardiola claimed earlier in the season that Sané did not do enough in pre-season to warrant a starting place at the beginning of the campaign. He also said after the FA Cup victory against Burnley in January that Sané was still making “big mistakes” in the defensive and simpler aspects of his game that needed ironing out.
