Anel is way way way overrated imo.
Half decent going forward and therefore a very good Championship player, but his weaknesses are exposed as he gets further to the food chain in English football as his strengths are going forward but not particularly defending which is a bit of a sod when he is spending a lot more time doing that as we are pushed back as a team every PL game. He isn't good enough for a top PL team either so it's really a case of being a top Championshio player in a team doing well in it, and a poor PL player in a struggling team.
Bottom line is he would be great for us again next season when we are back in the Championship, but then he seems to be a moody player who probably doesn't want to be around with us again back in the Championship, which is fair enough I suppose.
If we can get a decent fee for him then to me, it makes perfect sense to move him on. I like the lad but we could use the money he would bring in far more effectively. Don't forget he is one of the Newcastle 8 brigade and one of them whose head dropped like a trapdoor on the scaffold when it turned tough. I certainly wouldn't be upset if he's moved on. One of them I would look back on when his name was mentioned in the distant future and basically be indifferent about. Move him on, take the money and reinvest. Good for us, good for the lad and his Daddy.
