No I don't. I think you misunderstand what Moshiri and Ryazantsev did. They persuaded Raiola firstly that Lukaku should stay for at least one more year. However part of the deal was to put a price in the market for Lukaku - if you like a bit of a face saving exercise, given all the noises coming out of the Lukaku camp prior to the meeting. That price was set at a level no-one would bid at.
Had Lukaku wanted to leave, or had Raiola not wished him to stay, Lukaku would have been sold for considerably less than the £75 million figure given. He, his agent and his Father would have forced a move, regardless of Moshiri's stated intention of retaining players.
