£600k a week, he wont drop that wage. He's injury prone. This is why only Chinese clubs was coming in for him and no other big European team.
Zaha is easily one of the best players outside the top 6, I don't get why people wouldn't want a very good player who is an upgrade on our squad. A player who wants to join us, even when we don't have European football to offer (which will be putting off the cheaper alternatives on the continent). He's proven in this league, scores goals and wins a lot of freekicks / pens.
Prices of footballers have changed, £85m buys you poundland Michael Keane these days so £70m for Zaha isn't "that" bad of a price.
