Manchester United are set to table a take-it-or-leave-it £90million offer to Borussia Dortmund for Jadon Sancho, the UK Mirror reports.
United have been chasing Sancho all summer, but have been unable to agree a transfer fee with the Bundesliga club.
Dortmund have remained resolute on their £108m asking price for the England forward.
The Red Devils will now issue a final offer of £75m up front with a further £15m in add-ons.
United executive vice-chairman, Ed Woodward, will inform Dortmund there will be no negotiating over the fee or structure of the deal.
The Old Trafford side however face a battle to get the deal done before the October 5 deadline.
Earlier this month, United made a breakthrough in talks over Sancho's wages and the agents' fees, but have so far been unable to bring down the price for the England international.
