Keeper's friendly no shows due to mystery injury

Chelsea goalkeeper Petr Cech has suffered a minor injury setback ahead of the club's pre-season trip to Asia. The injury has seen the Czech Republic international sit out Chelsea's two friendly encounters against Wycombe Wanderers and Portsmouth this month. "I have been in regular training but had a small injury issue and we did not want to risk me taking part in those friendlies," said the keeper on his. "It was more just out of the safety aspect. There are three of us goalkeepers in the team, so we could afford it. "Otherwise, the pre-season has been going well and apart from [Michael] Essien and Alex, everyone else is fit. "[David]Luiz and Ramires are with Brazil at the Copa America but otherwise the squad is complete. For the mood it is good that we won both opening friendlies." And Cech, 29, hailed the performance of 18-year-old defender and compatriot Tomas Kalas during the 1-0 defeat of Portsmouth. "Against Portsmouth he made no mistake at all during the half," said Cech. "He did superbly, but he is not going to Asia because he is to take part in the European Under-19 Championships. "Chelsea is enormously popular in Asia and a big amount of people follow the Premier League, so I believe the matches will be played in excellent atmosphere."
