Chelsea are facing a defensive crisis ahead of their Champions League showdown against Paris Saint-Germain on Tuesday.

Guus Hiddink’s team thrashed Newcastle 5-1 on Saturday evening as they extended their unbeaten run under the interim manager to 12 matches.

But John Terry gave Hiddink an injury scare when he limped out of the clash at Stamford Bridge in the first half after a collision with Aleksandar Mitrovic.

Terry appeared to hurt himself when landing after challenging with Mitrovic in the air and, although he played on for a short while, the veteran defender was then substituted and headed straight down the tunnel for treatment from the physio.

It appeared to be a muscle injury in what could be a major headache for Chelsea ahead of their last-16 Champions League trip to PSG on Tuesday night.

Kurt Zouma has already been ruled out for the rest of the season after tearing his cruciate ligament against Manchester United.

Against Newcastle, Terry was replaced by Baba Rahman, who slotted in at left-back, with Cesar Azpilicueta shifting across to right-back and Branislav Ivanovic becoming Gary Cahill’s new partner.

A Pedro double and goals from Diego Costa, Willian and Bertrand Traore gave Chelsea their most comprehensive Premier League victory of the season.
