Barkley just represents talent at a good value these days. When you consider a comparable player like Siggy who is 5 years older is going for 50m these days. Barkley is just going to be a very low risk medium reward buy. Comparing him to one of the biggest talents in the entire world in Alli is a waste of time. If we only signed players who we have reason to believe could match Alli we'd be sitting on our hands for decades. We would never have signed signed Alli himself with this attitude.
