They're trying to hang on for dear life, despite him indicating he wants away.
You'd have thought they'd get more with 6 months on his contract as opposed to just going down the tribunal route once it expires.
Was a similar situation with us and Ince - Blackpool valued him at 8m. Tribunal ordered us to pay 1.6 - 2.3m subject to appearances (that he largely didn't make for us).
You could well be right. A quick Google doesn't suggest much in the way of significant sums at tribunal other than for young players who have played at international level. Still, for whatever reason, that seems to be the message at their end. Of course, money always talks and they're still working under closer financial monitoring until the summer window so a bid could test their resolve. Their owner will be putting out the right lines to keep supporters happy but everyone has their price.
