As I've said elsewhere, I'm not a massive fan of Clark, and I could have cracked his jaw if I had bumped into him in Germany in the Summer, but I'm a bit puzzled by your take on this, and others to be fair.
Doak plays in a position that we are literally completely bereft of anyone playing at any sort of level, the fact that he signed for Liverpool suggests that he's a very exciting talent and the fact that he's ripping it up week in and out at Middlesbrough currently would back that up.
At the time of Doaks selection, the convo would have been literally 'we need a bit of pace and width in the team, who have we got?' Doak and naebody else would have been the response...get him in and have a look.
Miller plays in a position where we currently, literally do not need him, ahead of him are players that play in Serie A and the English Premier and Championship, players that aren't completely over the hill and players that the manager trusts, rightly or wrongly.
Clarke will have watched Miller umpteen times and it's his job to decide if he adds something to his squad, and he clearly feels that at this moment he is right down the pecking order.
Clarke uses the word 'hype'...could he mean 'over-hype' and he's not buying into the praise that's been heaped on young Lennon so far?
