Manchester City winger Adam Johnson admits manager Roberto Mancini has "a temper".
Johnson was one of Mancini's first signings two years ago, although the 24 year old has recently found himself left out of the starting line-up.
"Roberto is eager for team to do well," said Johnson. "He is very emotional as you can see by his actions.
"But he is the same with the players, good or bad.
"He has a temper and whilst he doesn't have a United-style hairdryer, the fact is people have arguments. It is part of football."
