What about James Forrest? I've heard reports that he has potential. Our wingers are very good, but Davies and Duff are ageing, they may only have a couple of seasons left. Could this guy be a long term replacement (with some decent coaching and gradual introduction through cup games etc) ?
The last young winger that came through at Celtic went to Spartak Moscow for £9m so if you want him you'll have to pay. Forrest's a good prospect actually. Spurs are already trailing him. He doesn't have the tricks of McGeady but he's direct, good with the ball at his feet and, most importantly, knows how to finish.
I'm a fan of the greatest league in the world and Celtic so I feel qualified to respond. With their current squad, Celtic are a mid-table Championship side. However, if Celtic were to enter the English leagues they would be a solid EPL side very quickly. With Celtic's support and branding, Celtic could realistically aim for a top 6 finish and even CL football - and have a team that can actually compete in Europe and the CL. I would love to see both OF clubs in the EPL as it would enhance the league and, I think, put Scottish football back on the map.
