Martin Atkinson will referee this weekend's Premier League title showdown between Liverpool and Chelsea.
Jose Mourinho's side travel to Anfield this Sunday looking to close the gap with the table-topping Reds, who are currently enjoying a five-point lead as they home in on a long-awaited 19th championship and Atkinson has been elected the man to preside over the high-stakes clash.
The West Yorkshire official goes into this latest meeting, having already presided over three games for Liverpool - their opening day win over Stoke City, a 2-0 reversal to Arsenal in November and their 4-0 thrashing of Everton in late January.
He has also taken charge of two Chelsea matches this term, in their goalless draw against Manchester United and a comfortable 3-0 win over Southampton on New Year's Day.
Of the 30 Liverpool games Atkinson has refereed in the Premier League, Brendan Rodgers' side have won 14 and drawn and lost eight apiece. During their 2011 Merseyside derby win at Goodison Park, he controversially sent off Everton's Jack Rodwell for a challenge on Luis Suarez that was overturned on appeal.
Atkinson's 20 games in charge of Chelsea matches has seen them win 15, draw four and lose just one. He has overseen just one Premier League game between the sides - a 2-0 win for the Blues at Stamford Bridge in October 2009 - and a further two in all competitions.
