John Terry could be a doubt for Chelsea’s season opener against West Ham after being forced off in the victory against Werder Bremen.
Chelsea beat the Bundesliga outfit 4-2 in Germany but were dealt a blow when Terry had to be substituted late in the second half after suffering a blow to his head.
The captain now faces a race to prove his fitness ahead of the Blues’ opening Premier League fixture against West Ham at Stamford Bridge next Monday.
Last week new manager Antonio Conte had spoken of the importance of Terry’s experience and leadership ahead of the new campaign.
“John has always played for this club,” he told the Daily Mail. “I think he is in the history of this club. And it’s important for me that he can explain what it means to play for this club, what it means to wear this shirt, this badge. I think it’s important in the dressing room.
“I have spoken with him. In the future it’s important to have this relationship because he is the captain of our team and it’s important also to transfer sometimes message.
“I think to have a good relationship is very important with John and the other players, always with great education and respect.
“In every team there are some players with great experience. And I think this experience counts during the season. If you play but also if you don’t play, it’s important.
“The experience helps transfer the right concept to the team. And I must say John is a good example during the training session. He has the right attitude and the right behaviour, though I must say all the players have a good attitude in the training session.”
