There's just far too much guesswork there still. All we know is that at the moment he isn't playing. That may well change between now and the end of the season, and even if it doesn't, he may well stay. He also could be carrying a minor knock that we are unaware of. Even if he did leave, there's no certainty at all that he'd go to a team like Newcastle or Everton, or that he'd do well if he did. People got all misty-eyed over Makoun based on a funny jumper, a rap video and a half decent game against Man U, and he hasn't amounted to much since.
It wasn't half-decent, it was an excellent performance. A one off, sure, but an excellent performance.
