Chelsea boss Frank Lampard believes tonight's Champions League clash with Valencia will be decided in midfield.
The Blues cannot afford to lose if they're to reach the knockout phase.
Lampard said, "I expect a very organised team, a team with quality in attacking areas, the two strikers and the wide players they have. My feeling having played at this stadium, it's not just this team, it's the support and the atmosphere when they come together and they're playing well, it's a difficult game for everybody. I expect a difficult match.
"Champions League games can be a battle in midfield, they can be tight, they can be difficult, but you have to be clinical in both boxes, particularly when there is so much at stake and the match is tight."
