So you couldn't blame the 43-year-old former first-team coach for enjoying it when the travelling fans sang 'Keano, Keano, give us a wave' as he celebrated his first win as a Premier League boss.

It's a chant that until now was reserved in the top flight for Robbie or Roy, but the man who has been told by Blackburn's Indian owners that he'll be in charge at least until the summer is determined to make his own name.
'It's not about the fans singing my name, but it definitely lifted me,' he admitted after two goals by Nikola Kalinic and another from Mame Biram Diouf clinched the club's third away win of the season.

'I never thought there was any rebellion, but I was certainly delighted with the team spirit,' Kean added. Kalinic's goals were the added bonus - even though the striker was then sent off in the 65th minute for a reckless tackle on Paul Scharner.
The £6million paid by Allardyce for the 22-yearold from Hajduk Split had hung like a millstone round his neck during 36 nervous Barclays Premier League games that brought just five goals.
But on Tuesday he showed none of those nerves, scoring coolly after just five minutes as he ran on to Morten Gamst Pedersen's raking pass, then heading home from a 52nd minute corner.

'We have encouraged him to get into positions where he can show his finishing quality rather than spending too much time with his back to goal,' said Kean in what sounded like a dig at Allardyce's tactics.
Blackburn refused to buckle when Jerome Thomas met a cross from Somen Tchoyi to equalise, or when they lost Paul Robinson to injury.
West Brom have now lost seven of their last 10 league games, and their problems were underlined by Blackburn's third goal, a short corner routine in which El Hadji Diouf was given too much time to cross for Mame Diouf to head home.
And they were then reduced to 10 men when Gabriel Tamas hauled down Mame Diouf to stop him making it four.
West Brom boss Roberto Di Matteo said: 'We need to be better, to pay attention, to be focused for 90 minutes otherwise you are going to get punished.'
