Pep Guardiola told a press-conference on Tuesday that the midfielder will not play for the club again unless his agent apologises for comments made after he was omitted from City’s 25-man Champions League squad.
This raises the prospect of Toure pocketing the rest of his £225,000-a-week wage while only training with the club where he has spent the last six years.
Toure’s last appearance – and only one under Guardiola – came on August 24 in a Champions League play-off second-leg, where City already led Steaua Bucharest 5-0 on aggregate.
Between then and June 30, 2017 he will earn £9.9m for the final 10 months of his contract.
After joining the club in 2010, Toure has entered the final 12 months of a four-year deal that he signed in 2013.
Dimitri Seluk intensified the war of words this week by claiming that Lionel Messi made Barcelona, not the former manager Guardiola.
“The team he took at Barca had been built by Frank Rijkard and then he was lucky to have Lionel Messi,” Seluk told the Daily Mirror.
“It was Messi who made Barca, not Pep. Luis Enrique has shown that Barca’s success was not down to Guardiola.”
Guardiola won three La Liga titles and two Champions League crowns during his time at the Nou Camp, and followed that with three consecutive Bundesliga victories in Bavaria, but Seluk has questioned his pedigree.
“It was the same in Munich. He couldn’t fail. My grandfather could have won the league with that team,” he said.
“If Pep wants to prove himself as a great manager, then he should go to Zaragoza or Sunderland. Let’s see how good he is when he doesn’t take over a great team and hasn’t got half-a-billion pounds to spend.”
