Underage squads: Best Prospects

Agree with this, but would also add that he should be included on merit alone. Southampton are a good team and he generally plays ahead of Long and Obafemi (admittedly different positions) 

Hes a good player, in a position we definitely need cover. Next year will be massive for him.

Good to hear, he was pulling some good reviews in his Blackburn days too. So he's got some first team championship experience already. I can't help thinking (in hindsight of course) that the celtic move has been a year wasted.

Would really be good to see him break through to the first team next year at Celtic or a loan move to a championship club

They were never going to get into the first-team picture at an all-conquering Celtic side, expected to win every game. And Celtic don't compete in a proper reserve league. It was a complete dead-end move.

O'Connor's gone from playing regularly and impressing in Premier League 2 against the best young talent in England, being talked about in terms of first team opportunities at United and looking quite impressive on his Ireland debut, to toiling away for a basket case Partick at the bottom of the Scottish Championship - a league that isn't even fully professional.

Connell was playing regularly and garnering good reviews in the Championship. He's now playing a series of meaningless friendlies against  no-mark teams at windswept and desolate football grounds across Scotland.

It's an appalling waste of talent.

They play to win and have money to buy so no need for them to actively develop plays, like most teams do, when they can outbid all their rivals for players.
I appreciate all teams play to win and the fact that if they were good enough, they'd shine through but it seems Celtic is far from a nurturing environment and offers way less opportunities to allow them to impress.

Hope to see some of these 5 lads move out before the new season.

Frimpong is what's not right. When all of Celtic's established right-backs got injured and Lennon was forced to sink to the level of actually picking a young player, he had the choice between O'Connor and Frimpong. While I don't necessarily think there's a whole lot between them in terms of footballing ability, Frimpong has absolutely searing pace which was always likely to give him the edge in the decision.
