Frank Lampard is back in training at Chelsea with a view to playing against Liverpool in the second leg of their Champions League clash at Stamford Bridge on Wednesday night.

Lampard missed Chelsea's 2-1 Premier League win over Manchester United on Saturday following the death of his mother Pat from pneumonia last Thursday. But the England midfielder is understood to have trained on Sunday and is expected to be back with the rest of the squad today.

Meanwhile, it is understood that Chelsea have yet to receive a request from the Football Association for the CCTV footage of the post-match scuffle between a number of United players and their groundstaff.

United defender Patrice Evra is believed to have been at the centre of the row and the 27-year-old is expected to give his account of the incident to officials of the Old Trafford club today.

It is also believed that Chelsea and Manchester United chief executives Peter Kenyon and David Gill have discussed the incident.

The unsavoury fracas involved six of United's players, Chelsea groundstaff and several match day stewards. The players could find themselves facing disciplinary action from the FA who have already confirmed they want to see the footage.

The incident is believed to have been sparked when the players were asked by groundstaff during their warm-down session to run in the same direction as lawnmowers being used to trim the playing surface.

Evra, Gary Neville, Paul Scholes, John O'Shea, Park Ji-Sung and Gerard Pique were asked to run up and down the pitch instead of across it but tempers flared and a scuffle broke out.

In a separate post-match incident England centre-half Rio Ferdinand apologized to a female steward after catching her while kicking out at a wall in frustration.
