Plus there's additional goal bonuses, signing on fee's, appearance fees et cetera on top. Genuinely hard to fathom where it could have gone too, but it happens regularly. Emmanuel Eboue was another one recently.
He arrived at Parkhead in October and played a total of 77 minutes across four league appearances - that suggests he has major fitness issues.
If we were going to go after player who played for Celtic last season would much prefer it to be Saidy Janko, Nir Bitton or Tom Rogic.
