His set-piece taking ability will go to pot the moment he touches a Spurs shirt; it's just the natural order of things.
I know it's been said elsewhere but looking at the set of fixtures prior to the international break, we're looking at what could be a defining week results wise:
Everton v Arsenal
Palace v Leicester
Chelsea v West Ham
City v United
Spurs v B'mouth
No disrespect to B'mouth but I'd say that we have by far the easiest fixture of the lot. Come the beginning of April, Jan and Njie should be back which is a massive boost, and we'll be well positioned to really push for the title in the home stretch.
