While team-mates including goalkeeper Joe Hart were shown being consoled by opponents in the wake of Jerome Boateng's 90th-minute winner, Touré, who played under Guardiola during his spell at Barcelona, was pictured hugging and joking with the Bayern manager at the end of the game.
With Touré's subdued performance in the Allianz Arena proving to be his latest below-par display since angering the club's supporters with claims of unhappiness at the Etihad Stadium at the end of last season, the Ivory Coast midfielder now faces a battle to turn a tide of increasing frustration with his perceived lack of commitment to the Premier League champions.
One disgruntled City fan tweeted: "The quickest Yaya moved all night was to shake Pep's hand," with another claiming that "Yaya cuddling Pep, just not what we want to see after his performance tonight."
