The only thing we know is that he wasn't included in the matchday 18 when we had our three first choice central defenders and he was the only player with competitive experience at CB left on the books.
We also know that he's not been involved with the first team squad for most of the season. He was only given a squad number recently (when Colo may not have made it at OT).
Whatever the reason is, he needs to sort it out and get himself involved - this is exactly the opportunity he should be seizing to show how good he is/isn't. If he's not fit, he needs to get there. If he's not got the right attitude, he needs to sharpen up. If he's not been following directions from the coaching staff, he needs to listen and take heed.
Kadar is the only one who can do this - I struggle to believe that we'd allow a promising youngster to waste away if he'd been doing the right things and performing well in training. If he's not up to the mark, why should we extend his contract?
Agreed.
It is entirely down to Kadar to step it up and show what he can do and ultimately prove to Pardew why he should be in the first team squad. If he does leave at the end of the season, it would be an absolute shame considering his early promise.
