Sorry to see him go if he leaves during the current window. He does read the game (defensively speaking) very well. If IRC wasn't he the first signing to us following the takeover by the current owners? He realized quickly the vision that lay ahead and played a key role in the transformation that has taken place since 2009.
That said, his style of play with possession characterized the problems we had last season in terms of tempo. Even in the last two seasons in the Premier League - in general terms - the pace of movement in developing a counter attack or simply moving the ball forward through a fast series of flowing moves has been very evident. Our example against Newcastle last night was evidence of that.
If he ends up at Everton I cannot imagine for a moment that he would be a direct replacement for Fellaini. They are different in their style of play.
£4m would be the minimum acceptable bid that I would accept. He's worth circa £5m to £6m.
