If we were to sign Lennon Miller, and I don't think we will, then it won't be to loan back out for a season. If he was to sign it would be as a first team squad player for Celtic, playing around 30+ games for us. If we were to say to him we'll buy you then loan you out why would sign? He'll have offers to go straight into the first teams both down south and abroad. Whilst we are run by footballing dinosaurs there are many teams across the continent who are totally driven by data when it comes to signings, Lennon Miller is in the top 10% in Europe on all measurable matrices for 18 year old midfielders.
I doubt we've even approached Motherwell but we should do it now and if a deal can be done, do it. If not, wish the boy all the best and move on.
