I reckon DR wants a big wage hike to reflect his importance to the team. Doubling his wage, or even more, potentially. And probably the club have come in with a lower offer. He knows that if he goes to a big English club, he can get a lot more money, but there aren't many of those opportunities.
I agree with the general thoughts that it's only really United or Spurs when Conte crashes and burns. Or PSG, who knows.
He could go for a LOT of money when he leaves. Actually, we could be set to make an absolute fortune on the transfer market in the next couple of seasons unless we qualify for Europe. And why they hell not. Yes, there's a lot of competition now, with the top 6 plus Newcastle, WHU, and Leicester, but can you honestly say that we're considerably weaker in our first XI?
I think if we show we're gaining traction, DR will sign. Maybe then we'd sell Strak. Hedging our bets with these 2.
