We sacked himThis is very raw right now but in 6 months time clubs will be all over Thomas, especially ones in contention.
So given he was on his last chance, the club needs to make sure we get the best deal from his exit. If that means keeping him on the list so we can trade him at year's end, we should do it. If we have to pay him even 50% of his contract to completely cut ties, we won't receive any compensation but will still be out of pocket. That's not a good deal for us.
Better to just suspend him for the entire year to show we've punished his behaviour, keep him on the list but away from the club and make sure we receive compensation when we trade him.
