Chelsea are set to face Lille on Tuesday evening in a clash which will determine their fate in the UEFA Champions League.

The Blues currently sit in 3rd place in Group H and need at least a point against the Ligue 1 outfit to ensure of their place in the knockout stage of the competition.

Frank Lampard has been speaking to the press ahead of the game and he has delivered injury updates on both Antonio Rudiger and Fikayo Tomori, two key central defenders for the west London outfit.

Lampard confirmed that the Germany international is in the squad and ready to play, but the prognosis on the recently capped England international was less positive, per Sky Sports.

"He (Rudiger) is in the squad, so there's a chance," said Lampard. "It's good to have him back, he's been training really well."

But the manager confirmed that Tomori has a small strain around his hip area and will miss the game, though it doesn't sound like a long-term worry.

"The other news I suppose is that Tomori is out. He's got a small tiny strain around his hip area and it's been bothering him so I've taken him out for a few days."

Chelsea have enjoyed a glowing opening to the season under the 41-year-old but the positive atmosphere surrounding the club could be damaged by elimination from Europe tomorrow evening.

The return of Rudiger, however, could be the timely boost they need to secure their place in the last-16.
