Roberto Di Matteo salutes West Brom victory over Chelsea

Steve Clarke's side beat the European champions 2-1 at The Hawthorns to climb to fourth in the Premier League and spark a furious inquest in the Chelsea dressing room.

And Di Matteo reckons "anything is achievable" for Albion.

Blues players were heard rowing in the dressing room and one official claimed Di Matteo was overheard telling his players: "Call yourselves a Champions League winners' side and you can't beat them."

But the Italian, who led the Baggies back to the Premier League in 2010, paid tribute to Clarke's high-flying side.

They now have 23 points from 12 matches after their fifth home win out of six and are just a point behind third-placed Chelsea.

"You can see they have gained a lot of Premier League experience," said Di Matteo.

"There are a lot of players here from my time and they have signed a few good players too. They have goalscorers.

"At the moment, with the way it's going, anything can be achievable for them.

"Their home form is very good. Whether they can stay up there probably depends on how well they do away from home.

"Apart from Saturday, I am pleased for Steve."

Clarke paid tribute to his players after they beat the Champions League winners without No.1 goalkeeper Ben Foster and key defender Gareth McAuley, both injured.

He said: "Before Saturday's game I asked them a little question. I said: 'The good start's over; now we've got to build on it.' They gave me a really good answer.

"I've got a really honest group of players here. No matter what changes I make or how I shuffle the pack, the ones that have gone on the pitch have been different class.

"Saturday's game summed it up. There were moments when we had to play football, and we did.

"There were moments when we had to dig in in defence, and we did.

"Towards the end it was getting more and more difficult. Youssouf Mulumbu had seized up with cramp, so we were down to 10 men – but we defended for our lives."
