Ok failed is maybe wrong words.
For me he hasn't come on at all since his move. Hugely disappointed in him overall when he came back
Didn't think he was hugely effective in Premiership against better quality defenders.
Very one footed and predictable. Also doesn't look to have a lot of pace from standing start at Premiership level. Only looks threatening when coming inside when playing on the right wing but predictable that top class defenders just shift across.
Didn't start many games when Dreyer was here and wouldn't had Dreyer stayed.
Doesn't look English Championship level at all to me and predict that Derby will release him, injuries or not.
Morgan is a far better player, two footed with pace, can go either side and has a finish but IMO very doubtful he'll make it at top level either. Morgan does have the potential though.
Both of them outstanding Scottish Championship players but time will tell at higher level
