I'm getting annoyed that people are calling him a dud, raw and a waste of money. First, he's not even played for us competitively, so let's not judge in haste. Second, he's 23 years old, not 19 or 20. Third, he played 27 games for Lyon, which finished 6th in Ligue 1 in France, scoring 4 goals along the way.
Remember, there was a decent chance that we were going to lose Branthwaite over this past summer, so O'Brien in part was bought to cover that potential loss, and it seems clear that Branthwaite will leave next summer. Thelwell saw an opportunity to improve and be proactive and he jumped on it. The problem is Dyche not playing him. Maybe he'd find a place in Ireland's team if he got regular club play. I expect he plays vs. Southampton mid-week. And eventually he will be primary back up to Tark-Branth this year and a starter next year.
Don't want to correct you buuuuuut, he has played for us competitively, in the cup.
