He'd have to do plenty else on the field if he was only scoring 1 in 6 though.
Edit: If we are genuinely looking at him then I have no doubt the club knows exactly what they want from him.
He scored 46 goals in 146 games in his first 3 seasons at Spurs. 21 in 123 in his last 3 1/2 seasons.
Down from 1 in 3 to 1 in 6. I'd love the early incarnation but not so keen on the later one.
