The set could be set for a spell on the sidelines after going off the ball both sides of half-time in Stamford Bridge.

Chelsea face an anxious wait over the fitness of midfielder Mateo Kovacic and winger Willian following the pair went off injured in Tuesday’s FA Cup clash with Liverpool.

Kovacic seemed to be triggered slightly by Reds youngster Neco Williams before his foot was stood by Sadio Mane since the Liverpool pair tried to win the ball.

The 25-year-old originally carried on but went down back off the ball minutes later and had to be helped from the pitch. He was replaced by Mason Mount.

Later on, Willian sat himself on the turf with an unidentified problem less than five minutes into the second half, with Brazil-born Jorginho coming on in his place.

Frank Lampard’s side have Premier League fixtures with Everton, Aston Villa and Manchester City coming up in the next few weeks, along with the second leg of the Champions League last-16 tie with Bayern Munich.

If Kovacic is ruled from some of these games, his absence will be keenly felt in the Chelsea midfield.

The prior Real Madrid, Inter and Dinamo Zagreb guy was in fine form this year after enduring a frustrating first effort at Stamford Bridge.

Signed under Maurizio Sarri, he failed to make an impression in his first year in the club but has looked a different player for much of the season. He’s missed just four matches in all competitions, two of which came via a yellow card suspension.

Willian, also, has been an important player for Lampard this season and has not missed a Premier League match since the opening day of the season.

Truly, he scored the opening goal against Liverpool on Tuesday seizing upon a loose pass from Brazil team-mate Fabinho before hitting a powerful shot from the edge of the area which Liverpool copy goalkeeper Adrian spilled into his web.

The goal was his sixth of the season in all competitions, with five assists to his name also.
