Unless it's some earth shattering offer to like manage Barca or Real I think he'd have a hard time leaving. According to his wiki page this is what he had to say after leaving Plymouth for Leicester
I had a year out of football and had to think about what went wrong in my life. I was given some decent values from my mum and dad in our council house and one of them was honesty and trust and loyalty, and I forgot to do all that at Plymouth. I left them and I made the biggest mistake of my life. But I ended up here and it was the best thing I have ever done.
I know talk is cheap but if he's said that publically it sounds as though that he'd find it hard to turn his back on his players and the fans to leave for another job. 30+ points will usually ensure survival. 1/4 of the season gone and they're almost halfway to that total. They're looking **** good to stay up
