thats fair, but the same could be said for the first 20 games Theo played where he was a 16-17 year old and in and our of the first team.
If you want to look at just the last two seasons, Theo beats Bale in those stats as well.
Doesn't matter if Theo played at 16, he's always played an attacking position and it's not like Bale started at Spurs when he was 25. Bale has played almost a quarter of his PL career so far at a defensive position. If anything Bale has been the more productive attacking player, if you wanna go by stats.
