Grant: concentration gaffes may cost us glory

AVRAM GRANT insists Chelsea must learn how to concentrate for 90 minutes if they are to cut out the mistakes that could cost them the chance of glory this season.

Chelsea’s players have made uncharacteristic errors in recent weeks — allowing a 3-1 lead to slip against Tottenham and then gifting Fenerbahce victory in Turkey on Wednesday after leading 1-0.

German midfielder Michael Ballack has already voiced his concern over Chelsea’s mental fragility and Grant admits their aberrations always seem to happen when the team is playing well.
