Chelsea goalkeeper Petr Cech suffered a calf injury in training yesterday and could be ruled out for the champions' first game of the season against West Brom.
The Czech Republic international pulled up while running during a session at the club's training ground, and was taken for a scan to determine the damage, with his right leg covered in a protective boot.
Chelsea play against Manchester United in the Community Shield at Wembley on August 8 before starting the defence of their Premier League title against the Baggies on August 14.
Meanwhile, midfielder Deco spoke yesterday of his desire to return to his native Brazil, with a move to Fluminense. The club look set to release the 32-year-old Portuguese international from the final year of his £120,000-a-week contract because his young son David Luiz is seriously ill.
Deco said: “I want to return to Brazil most of all because of personal reasons but I am still in contract at Chelsea and I have to resolve that. I expect to have my situation resolved before July 26.”
One player who won't be leaving Stamford Bridge is Didier Drogba, with the Blues yesterday warning Europe's top clubs that the Ivory Coast striker is not for sale after he had been linked with a move to Manchester City by his agent Thierno Seydi, who claimed to have had talks with Eastlands.
“Today, he is at Chelsea but there might be some surprises before August 31,” said Seydi.
“The only direct contact I had was with Manchester City. We listen to everyone. He is 32 and open to everything.”
However, a City spokesperson said: “There has been absolutely no contact.
“We have not spoken to him and there is no foundation to this.”
And finally, Brazilian club Santos say they have rejected a £20m bid from the Stamford Bridge club to sign teenage striker Neymar.
