I think it's just a bit sad, like Peace thought the rules of 'I have to sell otherwise I'll have an unhappy player on my books, but if I let them go I'll reinvest the money' just didn't apply to them. But what ended up happening was exactly that. I think Peace thought he could act like a big club Chairman when he's at West Brom, and the rules are different.
As I said, maybe some blame lies with Berahino for letting his head go (in fact a lot of blame will lie there) but it seems like there was certain promises made to him that weren't kept. He also had his manager in the press saying he would like to sell to reinvest the money, but Peace thought differently. As it was, Berahino lost the chance to join an elite club, and you never know when those opportunities will come around again.
In fairness, Peace did nothing wrong. He's within his rights to do what he did. But if everyone's saying you should sell, lose an unhappy player and spend the money on players that can strengthen you, otherwise the brick will hit the fan, it's just a little bit funny when it actually happens to a club that acted bigger than they were against us.
And Berahino had two years left on his contract when we were bidding. So he could see the light at the end of the tunnel, and his value was only going to decrease rapidly. He knew that Peace could sell, but he also knew it wouldn't be too long until he got his move anyway. Modric had 5 years left and had no bargaining power. Maybe that meant Berahino should have busted a gut again for one more year, but maybe he was thinking it wasn't in his interest to perform as well as he could, because Peace would then place an unrealistic value on his head!!
