Of course Alan was sneaky - he was well known for as giving as good as he got. Nipping, standing on a foot, etc = was part of what made him such a terrific centre-forward. I remember Souness saying after a game v Blackburn - 'He's a bit of a bugger isn't he? I've got two big centre halves and he's messed them around - the bastard'.
Keane was a great player, but he was a snide.
