Think he has been much better recently. He looks sharper and fitter physically as well as being more nibble. You can actually see the improvements in his game as his hold up play (as we saw v Brentford away) is a lot better now v at the beginning of the season.
He also knows what it takes to win a title in the business end of the season thus he looks switched on and much better body language than say when we played v Liverpool at home when he looked like he was hiding.
Think he will be a big player for us for the remaining part of the season. Write him off at your peril.
