Might be playing other targets, bids in for Yoro and De Ligt.
They’d be stupid to bid 65+ for Jarrod when they are still working on fees for those.
Other thing they may be doing is hoping for disrupt our squad with uncertainty we go on tour next week.
Could also be trying to put us under pressure for time, in slowly incrementally raising the bid - they will know our transfer window will be shaped by this fee - as time goes by they will hope we blink if some of our targets if we sell move or it gets latter in the window.
