Mourinho keeping his feet on the ground

West Bromwich Albion's Neil Clement (R) challenges for the ball against Chelsea's Claude Makelele (L) during the Premiership match at The Hawthorns in Birmingham.

Chelsea manager Jose Mourinho said his team were "fantastic" after seeing them draw level on points with Arsenal at the top of the Premiership table following a resounding 4-1 win at struggling West Brom.

William Gallas's first goal for the club in 14 months set them on their way before strikes by Eidur Gudjohnsen, Damien Duff and Frank Lampard took Chelsea's goal tally to eight in two league games.

They head to Russia for Tuesday's Champions League clash with CSKA Moscow with confidence sky high after winning 12 out of 15 games in all competitions under Mourinho.

The Portuguese coach was clearly delighted with his side's powerful display at The Hawthorns, but quickly urged caution with the season still in its infancy.

Mourniho said: "We've now won 12 games out of 15 in all competitions with two draws and only one defeat. That's fantastic.

"We've cut Arsenal's lead at the top of the table by five points in the last week. But that doesn't surprise me. In Portugal when I coached Porto and we were five or six points clear I knew the Championship was over.

"But here in England it's different. Anyone can beat anyone. But all we can do is carry on as we are doing and see where that takes us.

"It's nice to score a few goals but we're not playing any better now than when we weren't scoring."

Chelsea never looked back once they went ahead through French defender Gallas's close range strike on the stroke of half-time and three second-half goals by Iceland striker Gudjohnsen, his ninth for club and country, Duff and Lampard earned Mourinho his biggest away success since taking charge in the summer.

Mourinho hinted that he may use the midweek trip to Russia to rest some of his high-profile players.

England international Lampard was substituted after making his 118th consecutive Premiership start and could be one of those who is given a break before the home game with Everton on November 6.

West Brom are clearly a club in turmoil. Frank Burrows took charge of the team after Gary Megson, manager for the last four-and-a-half-years, was relieved of his duties following a row with chairman Jeremy Peace.

Former England coach Glenn Hoddle is the favourite to take over but whoever lands the job will have plenty on their plate.

West Brom look favourites for relegation after just one success in their opening 11 games since winning promotion, and head for Southampton next weekend having conceded seven goals in two games.

Even a consolation goal by Hungarian captain Zoltan Gera failed to bring a smile to Burrows's face.

He said: "I have told my players that they have to stand up and look at themselves. We didn't deal with the responsibility in the second half.

"That said I think Jose Mourinho has put together a very good team in a short space of time and that's not easy.

"I have no idea whether I will still be in charge by the time we play at Southampton," said the former Portsmouth boss.

"You will have to ask the chairman. He's the only person who can answer that."
