Comfy win by Chelsea yesterday now puts Tottenham under a little bit of presure and unsecurity on whether or not they'll manage to keep their current 5th place in the table.
The Spurs have lost 3 games in a row and reduced their gap over 6th Man United to 6 points, which is not really a safe position, as Tottenham is playing Liverpool next and Man City on 14th, so most likely they'll lose 6 points there.
The good thing for them is, that even if they get overtaken by Man Utd, they'll still participate in the Europa League next season, as the winner of the FA cup (Man City or Man Utd) will earn an EL spot, but if they qualify for CL or EL by high league position, that spot would be transferred onto 6th place. With that in mind, Tottenham doesn't have that much at stake, other than pleasing their fans and a better in the Premier League rewards.
