Gus Poyet has good reason not to remember our 1-0 victory over West Ham at Upton Park in late November - his assist to Les Ferdinand's goal left him seeing stars.
The livewire midfielder suffered a terrible clash of heads in the build-up to Les' goal and was knocked out cold for several minutes. So can he actually remember anything of the game?
"One half I can!," laughed Gus. "And until the ball was going wide for Simon, the rest I watched on the television.
"It's a good one to remember, we won, we played quite well in the first half and then I got the knock on my head.
"I didn't realise how bad it was really until people were telling me afterwards that they were really worried because I was completely, 'gone'.
"I have had a couple before, but not like this, it was the longest time I have been out cold. I wanted to play on, it is my normal reaction, I want to play all the time."
Gus confesses that this is one London derby that the players really enjoy taking part in because of the way both teams try and play football.
"There are too many London teams! The good thing about this game is that we can enjoy, there will be goals for sure, but we need the three points to finish as high up the table as possible."
