With that in mind, Brentford’s valuation of Wissa is emerging as a factor in his future.

Brentford have no intention of losing both Mbeumo and Wissa this summer but, in reality, with Wissa turning 29 in September, the scenario of a depreciating asset – who this summer could command a fee in the region of £40m, if not more – will likely be a consideration.

That he has just 12 months left on his current deal, though there is an option to activate by a further year, is another factor to mull over.

For all parties, there appears merit to finding a resolution – whether a sale or a contract renewal – sooner rather later.

It has been a summer of upheaval at the Gtech Community Stadium – manager Thomas Frank joined Spurs, goalkeeper Mark Flekken was sold to Bayer Leverkusen, captain Christian Norgaard has left for Arsenal and now star forward Mbeumo is set for a move to Old Trafford.

Brentford have already started the process of replenishing their forward options with an unsuccessful £35m offer made to Ipswich for attacker Omari Hutchinson.

They also extensively watched Bournemouth forward Dango Ouattara last season.

No matter how Wissa’s future develops, it will be a challenging start for new boss Keith Andrews who is preparing for his first season as a manager at any level of professional football.
