English outfit Manchester United are set to present a final offer to Brentford in their bid to sign Cameroonian striker Bryan Mbeumo.
The Premier League giants have pursued the 25-year-old for the past month, submitting two previous offers.
The most recent offer was a £55 million plus £7.5 million in add-ons offer that appeared to have been turned down.
Brentford insist the previous offers were below their valuation of the attacker and are demanding more.
Mbeumo, a key figure for both club and country, is reportedly keen on a move to Old Trafford.
With pre-season preparations fast approaching, Manchester United are eager to finalise the deal and integrate the striker into their squad ahead of the new campaign.
Sources close to the negotiations indicate that the Red Devils are unwilling to prolong talks beyond this next offer.
Should Brentford reject it, United are prepared to walk away from the deal entirely and already have some other targets in sight.
