I think Foden is currently a much more suitable option for opponents who will give us opportunities for counterattacks. If the team's insistent on sitting deep against us then I'd rather we have David to pair with Kev.
Interesting one that because i think Foden will score more than any of them. He's got the ability to beat a man on the edge of a packed box and get a good shot away. Something i think we lack quite often.
