"They’ve still got that but they’ve added the likes of Oscar and Eden Hazard and Juan Mata is into his second season and coming along nicely. They’ve got clever players who can play in the pockets and make it difficult for teams.

"I don’t know why we’ve found it so tough [at Stamford Bridge]. In the 90s we used to go there and win quite regularly.
"Last year we can take heart from how well we played and I think we probably deserved to win. We came back from three goals down and managed to draw 3-3. Also, in the Champions League a couple of years ago, we played well and won. I think we’ve shown good form there in the last few years but just haven’t got the results we’ve wanted."
