I’m not directly comparing them, I’m saying that they definitely have the budget for the fee and wages, that’s all. Of course they’re trying to negotiate a better deal, who doesn’t want two players for the price of one.
If they have FFP issues, they’ll have to get Henderson to reduce his wages in line with playing for a smaller club.
But your original point was saying it weakens their negotiating position because of them giving Lingard a contract last season which really doesn't have any relevance to the situation. It's different scenarios. This is them purely wanting to negotiate to try and get the best out of their summer. They already paid Hendersons wages last year, the point of them negotiating is to try an get a better deal.
