Manchester United manager David Moyes has admitted that he still gets angry remembering his last encounter with Manuel Pellegrini when he was at Everton, who lost to Villarreal in 2005.
According to Sky Sports, the pair goes head-to-head at the Etihad Stadium on Sunday in their first meeting since 2005, when Moyes was at Everton and Manchester City boss Pellegrini at Villarreal.
The teams met in a two-legged Champions League qualifying round tie and the Spaniards won both games 2-1, the report said.
In the second leg, when the score was 1-1, Everton striker Duncan Ferguson scored with a late header, only for referee Pierluigi Collina to rule it out, the report added.
Manchester United face Manchester City in a derby match at the Etihad on Sunday, with Manuel Pellegrini now being in charge of the City team.
