Ferguson, looking ahead to Sunday's match, added: "I'm

hoping for a draw. We've got an advantage, that's all.

"We can't say it is a great advantage with the number of games we've got left But we would rather be top of the league th an anywhere else."

Arsenal manager Arsene Wenger was left to lament more lost points with Saturday's draw at home to the Hammers following the 1-1 result at Everton in midweek

"We tried until the end but it didn't come off. We just lacked a little sharpness and creativity to get away with the three points," saldWenger.
