It's definitely a lose lose, I can see both sides of the coin on this one, the extra year that the club want ( in theory ) shouldn't really effect KLP long term as if he's good enough then people will come in and buy him anyway and he gets to repay the club a little that's supported him since age 8 by getting them a larger transfer fee. But from a purely selfish point of view ( and we don't know if it's him or his representative ) he can walk away for free sooner if he gets a shorter contract and get ( potentially for him and or his representative ) a larger signing on fee.
I can see grants/the club's point when he said they want a little bit more commitment from a lad who the club has developed since age 8 and thus a bigger fee potentially and I can see KLPs point also re move on sooner and easier. If KLP was older and his next move was potentially his last move and chance for bigger ££ etc then I really wouldn't begrudge him wanting a shorter contract etc. But at his age and development stage, the fact he's still in his breakthrough season etc, I think he's being a little short sighted if that's the right phrase or potentially badly advised.
What there is no excuse for at all, is the way it's been handled media wise by grant / the club. I would say it embarrassing and shocking, but it's just the norm for us and the idiots at the top
