Looking at the table, I think there is a good chance the top 4 will stay how it is at the end of the season. Spurs, Chelsea & Liverpool are all dropping points regularly, and that is just not good enough when Newcastle haven't shown much signs of letting off their foot off the gas despite 1 draw with Leeds. Man U are certainly found something in the tank to grind out 1-0 wins and keep clean sheets, even with Shaw in centre back.
Liverpool just have too soft a centre, their midfield can get overrun and then that put far too much pressure to the defence.
Chelsea, I am not sure what they are doing but they are not clicking, Spurs just can't defend, period.
At this rate I think Brighton and Brentford would be challenging with them for the 5th and 6th spot. Actually I think Villa too could do something, they are only 4 points behind Chelsea now and they have turned a corner it seems.
