Chelsea are expected to list more flashpoints from the fracas involving a member of their groundstaff and Manchester United defender Patrice Evra today when they submit their report to the Football Association.

Evra clashed with groundsman Sam Bethell last month after Chelsea's dramatic 2-1 win at Stamford Bridge which sparked a melee between players, coaches and stewards. In a separate incident, fellow United defender, Rio Ferdinand, lashed out in the tunnel after the match and kicked a female steward. The England international has since apologised and sent a bouquet of flowers to make amends for his mistake.

However, insiders at Chelsea revealed that their report will include more complaints and they have drafted in their top barrister, Jim Sturman QC, who represented the club during Ashley Cole's tapping-up inquiry.

United, meanwhile, are expected to claim that Gary Neville and coach Mike Phelan heard abusive comments from Chelsea's groundstaff about Evra.

The FA disciplinary committee are expected to scrutinise the reports from Chelsea and United and will review CCTV footage of the incident. However, it will be difficult to identify what caused Evra's angry reaction, as he is understood not to have heard the comments first-hand.

A decision is unlikely to be made before the Champions League Final in Moscow.

The clubs have clashed in the past. Chelsea chief executive, Peter Kenyon, quit United to take up his role with the Blues, while opposite number David Gill once served a legal letter following John Obi Mikel's transfer to Chelsea.
