Steve Bruce believes there is a responsibility on all Premier League managers to be wary of their touchline behaviour in the aftermath of Alan Pardew's admission of improper conduct during Newcastle United's win at Hull City last weekend.

Pardew, 52, was sent to the stands for a head-butt on Hull midfielder David Meyler and later apologised but has since been hit by a £100,000 club fine and has accepted the Football Association's charge.

"All of us have done stupid things. Whether it is running up the touchline in celebration, or berating somebody, afterwards you sit back and go: 'Aw, what have I done that for?' The coverage of the Premier League now means it is scrutinised all around the world and the one thing we don't want is to see images like we saw last week," said Hull manager Bruce, ahead of Sunday's FA Cup quarter-final against Sunderland.

"Alan would be the first to understand that, and we now let the authorities make the right call on the punishment he will receive. We were all shocked at it and Alan has got to pay the consequences for that, maybe look at himself and say there have been too many incidents that he has got involved in."

In September 2012, Pardew was given a two-match touchline ban and fined £20,000 for pushing assistant referee Peter Kirkup in Newcastle's victory over Tottenham. But the FA are expected to mete out more severe punishment for this misdemeanour.
