Pep Guardiola has advised former employers Barcelona "don't talk too loud" about Manchester City's breach of UEFA's financial fair play regulations in response to comments made by president Josep Maria Bartomeu.
City were banned from the UEFA Champions League for two seasons and fined €30 million (£25.1 million) after European football's governing body said the club overstated sponsorship revenue between 2012 and 2016.
Barca chief Bartomeu told reporters on Tuesday that he wanted to "thank UEFA regarding FFP" and praised the organisation for its "fantastic work" in recent years, per Reuters (via ESPN FC).
