Mateo Kovacic is likely to miss Chelsea’s Champions League semi-final first leg against Real Madrid.

The Croatia midfielder has missed the Blues’ last three matches after picking up a hamstring problem on the eve of the Champions League quarter-final second leg against Porto.

The 26-year-old has been ruled out of Saturday’s Premier League trip to West Ham, and boss Thomas Tuchel has admitted the former Real star will be hard-pressed to face his old club in Madrid on Tuesday night.

“He had two clean sheets in two difficult matches for us.

“So it is a very good feeling to know we can rely on two goalkeepers and they can produce clean sheets.

“They have earned our trust in the moment and the situation in general has not changed, Edou will be in goal tomorrow.”

Chelsea have also revealed plans to install rail seating at Stamford Bridge next season, while general admission season ticket prices have been frozen for the 2021/22 campaign.

“A further upgrade to Stamford Bridge that we are pleased to announce is the installation of rail seating in the Matthew Harding Lower and Shed End Upper and Lower tiers,” read a Chelsea statement.

“This change, which will be ready for the 2021/22 season subject to approval by the Sports Ground Safety Authority (SGSA) and its Safety Advisory Group (SAG), will enhance supporter safety by replacing the current seats in those sections of the stadium.

“The decision is the result of many months of consultation with the SGSA and Hammersmith and Fulham Council, as well as work with independent architects to find the optimum solution for Stamford Bridge.”
