Chelsea playmaker Mason Mount was forced off on his Champions League debut after a shocking tackle from former Arsenal star Francis Coquelin.
The Blues youngster, who has been superb in his opening five Premier League matches this term, was substituted by Frank Lampard after just 16 minutes of the clash at Stamford Bridge.
The Valencia midfielder caught Mount on the ankle with an X-rated tackle, and despite his best attempts to continue the England international could not carry on.
Mount was then replaced by Pedro.

Coquelin escaped with just a booking despite the dangerous nature of his tackle.
The French midfielder was kown for his hard-hitting tackles during his 10 years at Arsenal between 2008-18.
And the injury will come as a frustrating blow for Mount, who admitted it was his career goal to play in the competition prior to the match.
He said: “It is a dream to play in the Champions League and, for me playing in it with Chelsea, it is a massive game.”
“Watching that as a kid, it gives you the extra fire and the goal to want to play in the Champions League because you have seen what the club has done before.”
