After the CL final in 2008 somebody on RAWK said that the players were singing "We won it three times without killing anyone" with the fans. Somebody mentioned that they had a video (that conveniently nobody there has ever provided) showing the players singing those words, and after this some Scouse journalist mentioned it and ever since then people there quote it as a fact.
In fact, there is a video clip on the 07/08 season review DVD showing a few players (Nani and Anderson were definitely two of them there, and from what I can remember I think the others were Brown, Fletcher and O'Shea) singing "We won it three times" along with the fans, but that's all they sing, they stop when the fans get to the "without killing anyone" part. Nani and Anderson carry on, but it's clear that they aren't singing the right words, not just at that part, but the whole song. Obviously due to their lack of English abilities.
If anyone has the season review DVD from that year and wants to check, it's right near the end.
