Chelsea defender Andreas Christensen was taken off in the first-half of his side's Champions League round of 16 second-leg against Lille in France. The Denmark international went down with what looks like a muscular injury.
Trevoh Chalobah was brought on by Thomas Tuchel in Christensen's place, to play alongside Thiago Silva and Antonio Rudiger in the Blues' defensive line. It was a frustrating opening half an hour for Chelsea, with Christensen's injury only adding to that.
In fact minutes later, Chelsea gave away a penalty, following a handball from Jorginho inside his own box. Jonathan David stepped up from 12 yards and converted the ball past Edouard Mendy.
