It seems Manchester City manager, Pep Guardiola, has several dark clouds gathering over his head, and the latest thunderclap of criticism comes from venerable footballer, Yaya Toure.

The 37-year-old, former Man City midfielder told a sporting news outlet that Guardiola should have bagged the UEFA Champions League title, calling the 49-year-old Spaniard’s campaign failure “strange and disappointing”.

Manchester City lost 3-1 to Lyon in the quarter-finals last week. Many expected Guardiola’s squad to advance to the final but instead spiralled into a humiliating defeat, with much criticism aimed at the coach and his tactics.

Toure said: “Everybody knows [Guardiola] is a great manager, but at the moment, when things aren’t going their way, sometimes is it time maybe to change? I don’t know, we will see.”

He and Guardiola endured a strained relationship across two clubs – starting with Barcelona in 2007, and ending with City confirming in June 2010 that the Ivorian would be leaving.
