EPL: Liverpool -vs- Arsenal

Liverpool is still top of the table, but Chelsea has a game in hand, and Man U has two. Aston Villa continues to rise as well. Do the reds have enough to remain on top? Rafa is close to a new deal, are they simply playing the waiting game until the January transfer window to bolster their attack and make the final push? They certainly didn;t look like world beaters against the Gunners this morning, squeaking out a draw courtesy of Keane's brilliant/lucky blast . Are Chelsea and Man U poised to make the 2nd half run and spoil the dream start for Anfield faithful? As a Liverpool fan, I'm getting a bit nervous!
