â€śSometimes it is difficult to judge centre-halves over just one or two games because they can only play as well as the strikers theyâ€™re up against. If they donâ€™t have too much to do itâ€™s difficult to see how good they can be,â€ť Berg told the Manchester Evening News when discussing Keane's performance in the U21 final against Tottenham.

â€śThey were playing against decent strikers. Harry Kane in particular is a very good player."
