Critch says he sees him as a wing back ...
"He’s someone who I’ve seen since his U18s days at
Middlesbrough, he was in a very good team there and played in the UEFA youth league. I came up against them during my time with Liverpool.
"He’s had different loans out in the football league, and has been in the Scottish Premier League. He’s got real quality on the left side, and has really good endurance. I think he’ll give us real quality. I see him as a wing-back, he can open up the pitch for you. We’re hoping he can bring some balance.
"He’s really good on the ball and makes good decisions. He’s got ability in his left foot which we believe will provide us with a different dimension in the second half of the season.
"We’ll see what happens with other players in that position. Any time you bring someone in, the likelihood of others departing increases. If players are unhappy with playing time then that’s a conversation we will have. If we can’t offer regular game time, and someone else can, then if it’s right for both clubs we’ll discuss it.
"The competition allows us to pick different players for different games, and different parts of games- which is important.
"We’re still looking elsewhere this window, but that may depend on what happens internally. We’re always keen to provide an environment where we coach our players to improve- no matter what age they are.”
Coulson could be in line to make his Seasiders debut in the EFL Trophy tie against Burton Albion on Wednesday evening (K.O. 7pm).
"He is eligible to play,” Critchley added.
"He’s a good age and had plenty of exposure at Aberdeen last season. It’d be foolish to think he’s going to play every minute of every game, but hopefully he stays on the pitch and he’s fit enough to make a big contribution for us.”
"He’s not played loads of football so it’s something we need to take in consideration. He came off the bench for Middlesbrough against Aston Villa in the FA Cup. He’s been training every day.
