Mancini was insulting players on day of title win onuoha

It seems like you're referring to a specific incident involving Roberto Mancini, the former manager of Manchester City, and the Nigerian footballer, Taye Taiwo Onuoha.

On May 13, 2012, Manchester City won the Premier League title after a dramatic finale, beating Queens Park Rangers 3-2 at the Etihad Stadium. However, according to Onuoha, who was a player at the time, Mancini had a heated argument with several players, including Onuoha, in the dressing room before the match.

Onuoha, who was not a regular starter under Mancini, claimed that the manager was "insulting" and "belittling" the players, which led to a tense atmosphere in the dressing room. Onuoha took to Twitter to express his disappointment and frustration, stating that he was "disappointed and hurt" by Mancini's behavior.

Mancini later denied the allegations, saying that he was simply trying to motivate his players to perform well in the crucial match. However, the incident has been widely reported and has left a lasting impression on the players involved.

It's worth noting that Onuoha has since spoken publicly about the incident, stating that he has forgiven Mancini and that the two have since made amends. Despite the controversy, Manchester City went on to win the title that day, and the incident has become a memorable moment in the club's history.
