It was a case of Peter replacing Paul last week with former striking legend Paul Goddard leaving the club and Peter coming in as Alan's assistant.
"He only really had a couple of days with us but he is an infectious character and he never stops talking," he says.
"He will drive everyone mad, but in a positive way."
Peter spent the first half of the week on a course and Alan says:
"He has up doing the Scottish Pro Licence this week until Wednesday and he will be back for Thursday.
"It is a new start on his part and he wants to take his opportunity.
"Let's hope that great start with the away win at Wolves continues."
For what it is worth Sunday's game, was the first cup meeting with Wolves since a second round clash in 1910, when George Webb scored a hat trick and Danny Shea hit two to give West Ham a victory.
It was not, as has been reported, the first time the two teams have met in the FA cup, but it is still remarkable that the two clubs had not faced each other for 94 years.
West Ham did play at Molineux in the FA cup more recently, though - in 1933, to be precise.
Vic Watson scored in a 2-1 defeat by Everton in front of 37,936.
