Sunderland boss Martin O'Neill wants revenge today at Chelsea.
Back in 2010, O'Neill suffered a 7-1 defeat as Aston Villa manager at Stamford Bridge.
He said: "I went there with Villa and we ended up getting heavily beaten by seven goals, which I have to say was entirely down to myself still keeping our attacks going when we were 4-1 down.
"But in terms of the final scoreline it was my worst defeat.
"On the day it felt pretty poor. When it got to 6-1, I felt maybe it wasn't the best idea to have kept attacking them after all.
"Sunderland's result down there last time out was fantastic but mine wasn't quite that good. At least I'm in decent company with a result like that. Arsene Wenger got beaten 8-2 at Manchester United this season and Alex Ferguson lost 6-1 against Manchester City." "We went into that game with the best defensive record in the country.
