Probably a good move all round - providing there are assurances he gets playing time.
With Son, Richarlison, Werner, Johnson . Solomon and Kukusevski, playing time would be restricted at Spurs.
The few minutes he might have got will now be shared between Scarlett (who Ange seemed to like in pre-season) and Donley who has now had a few appearances with up to 15 mins/appearance and maybe Santiago who has now been on bench quite a few times.
I imagine Gil will be out on loan for similar reasons
