Chelsea boss Avram Grant's dithering in substitutions has been brought to light ahead of today's huge game against Arsenal.

The Sunday Times says Chelsea's players tell a tale from the Champions League tie away to Olympiakos in mid-February, when the poverty of Chelsea's performance in a sterile goalless draw caused consternation on the bench.

"We've got to get Frank Lampard on," Grant was told. "Yes, who for?" the manager said, turning to his coaching staff.

"Ballack," said Henk ten Cate. "Essien," said Steve Clarke. Grant then took an eternity making up his mind and, to Lampard's disgust, the change [Ballack went off] was delayed until the 86th minute, much too late to have the desired effect.

However, despite the doubts over his ability to handle big games, Grant's estimation in the Premiership will go up ten-fold if he can manage to beat Arsenal today.
