Chelsea midfielder Frank Lampard returned to training Sunday for the first time since his mother's death, suggesting he may be back to face Liverpool in the Champions League.

After Pat Lampard died from pneumonia on Thursday at age 58, her son has been allowed to stay away from training and missed Saturday's 2-1 victory over Manchester United in the Premier League.

But he could now return for Wednesday's second leg of the Champions League semi-finals against Liverpool, which is tied at 1-1.

A member of the Chelsea staff speaking on condition of anonymity told the Associated Press that Lampard participated in Sunday's training session and was touched by the outpouring of grief from the club.

Michael Ballack's opening goal on Saturday was celebrated by the squad holding a jersey emblazoned with Pat Lampard's name.
