Tommy Doyle needs game time there's no way at this time he's getting any games here, even if he does it'd be in a deeper role and he's a box to box midfielder who needs to play in his desired role... Doyle isn't the type who can learn and improve by having even a dozen sub appearances, he needs game after game to grow and stamp his authority for a team.
We probably wouldn't even let the likes of a young Steven Gerrard or Frank Lampard in our team cos of their style differences, we want a silky centre midfielder and a deep lying midfielder no all out action that's solely Kev's role and we trust Bernardo to deputise if he's out so Tommy Doyle's favoured route has always been blocked, even if he played we'd still be restricting his style a loan anywhere is absolutely perfect for him and what he needs... He needs to be in a lessor league and try to be some teams version of Kev to grow, with him being an energetic all action central midfielder he needs this... only thing I'd say is this loan should've happened last season at championship level or even league 1 for a Sunderland type team.
I think it's a fantastic move for him if they give him license to roam and be a proper Box to box midfielder, he's a hard worker and needs to be in that league he'll thrive and be a far better player for it.
The bundesliga 2 looks quite competitive this year according to German media, their fans are said to be initially unimpressed but the Hamburg midfield has been pretty lethargic in recent times, they might not realise they're desperate for a midfielder of his type and if it works out this season and they promote it could be a 2 year loan... If they promote and he shines in the top flight it could do his chances here the world of good, if he doesn't make it here but does all that he'll develop into a good Prem player and gain us a fairly decent transfer fee.
