West Bromwich Albion manager Bryan Robson has said all week that Saturday's spat with Jose Mourinho was behind him.

That line of thinking became official yesterday afternoon when Albion were cleared of any blame for last weekend's events at The Hawthorns and were told by the Football Association that they have no case to answer. It left Robson free to concentrate on another Saturday's match at St Andrew's against relegation rivals Birmingham City.

Chelsea, however, have been charged with failing to ensure that their players conducted themselves in an orderly fashion, with particular regard to the mob that surrounded referee Mark Halsey following Ronnie Wallwork's first-half foul on Claude Makelele.

It is a surprise that this should be the game's only incident to come under FA video scrutiny - and it will be considered by many that Chelsea manager Mourinho has got off so lightly. But, as far as Albion are concerned, the FA will not be taking any formal disciplinary action and they consider the matter to be closed.

Many believe Mourinho got his comeuppance in Barcelona on Tuesday night.

Robson was never seriously expected to come under further scrutiny for his part on an afternoon when ugly scenes were triggered by Mourinho's pitchside antics.

The Albion boss is more concerned with this week-end's match.

Saturday's lunchtime showdown at St Andrew's is the Midlands' biggest game of the season.

Although nothing will be decided on the day, the stakes are massive, especially if Robson's team wins and puts his old mate Steve Bruce and Blues in even deeper trouble.

Last term's visit brought an embarrassing 4-0 defeat. But there are expected to be only three survivors from that game in the Albion lineup on Saturday - Neil Clement, Nwankwo Kanu and Jonathan Greening. Robson wants the memory of last season's great escape to motivate his team.

He said: "I hope the experience of last season will help us. But I also hope that the lads will not think it is just going to happen again for us. We have to make it happen.

"Most managers will think if you haven't got to 34 points by now you're a bit concerned. And there are a few managers in that position. But we have to get some good performances so we can open a gap, to give us a cushion for a week when we are out of form."

Robson also believes that the pressure is firmly on Blues, saying: "The expectations of the Birmingham fans at the start of the season were about challenging for Europe, maybe. They did not expect a relegation fight. All West Brom fans, realistically, would have said that they were happy staying in this division.

He said: "I've always said, since I joined the club, that the fans play a massive part.

When the players are not producing in home matches, if the fans get anxious, that can translate to the players. But when you have a terrific atmosphere, like it was on Saturday, that can really help the players."

But, most of all, Robson says he is still enjoying being part of another Baggies' survival battle. He said jokingly: "The past 18 months has aged me about six years. Two relegation battles in two seasons is not relaxing, let's put it that way. But it's part and parcel of the game.

"And I've just enjoyed being back in the game and managing a football club again. I enjoy the banter with the lads. I enjoy being out on the training pitch with them. Really, just getting improvement out of them is good. A few have improved and, as a manager, that is my job."
