Pep Guardiola has come under attack by former Manchester City icon Yaya Toure, who branded his ex-boss as a "snake".
The pair, who worked together at both FC Barcelona and Manchester City, have had a fractured relationship since 2010.
As Barcelona boss, Guardiola opted to drop Toure after promoting Sergio Busquets from the B side, leading to the midfielder's sale to City.
Busquets, who was seen as a better fit for the 4-3-3 system, went on to cement himself as a club legend, winning a total of 32 trophies during his 14 seasons with the first team.

The pair had similar difficulties when Guardiola joined City in 2016, where he cut Toure's playing time once more.
Appearing on the ZACK YouTube channel, Toure described his former coach as a "snake".
