That's a fair assessment. But imho, he shouldn't leave just yet and give it one more season after this if ever they don't win anything. Do you remember when Bale left for Real Madrid because Tottenham only finished 5th? If he hadn't left there was a big chance they would finish top 4 under Andre Villas Boas as the team would still have some stability. When Bale left, they acquired around 6 new players in and this affected their style and stability on the pitch. There was just too many new faces in the team and it was like they were trying to find their form all over again.
