I would be amazed if he didn't at least see it through to the end of the season.
He could put his name in lights (even more so), and then name his price at any club, if he could get us into the Champions League given what he walked in to (the outsiders view of what he walked into anyway)
He's in a no lose situation. I also think he's a man of his word though and will probably even see out his contract at the very least
