It stalled because of a legal dispute.When did he say that?
Because Considering the last time I remember him saying it was 3 weeks ago and the transfer stalled, I can believe the reason it stalled was they wanted a higher buyout fee.
£50m is the upper limit of fine but it's still fine. If he's good enough for us to want him when Agüero goes back to Argentina in 2019 then he's worth more than £50m and a hell of a lot more than the net £25m.
