Their game is significantly different though: Dele being more about technique than explosive speed.I think Dele has buckets more natural talent than Bale had at 19/20. Bale got good through hard work, even his athleticism was down to training on the right things and his technique improved a lot in his time with us through hard work perfecting it. If Dele can replicate that effort then he can become the better player I have no doubt.
However that's no bad thing - I agree Dele may well have the higher ceiling and less dependence on pace should give him a longer career with fewer injuries.
