Man Utd angry with Brentford for two major reasons as shock new details of Bryan Mbeumo deal emerge

Manchester United are reportedly angry with Brentford for two key reasons after finally completing the signing of Bryan Mbeumo.

After a long-running saga, Mbeumo was confirmed as a United player on Monday evening, just in time for the club's pre-season tour of the United States.

The 25-year-old has signed a five-year deal at Old Trafford, with the option of a further year.

He has joined from Brentford for an initial fee of £65 million, which could rise to £71 million if all the add-ons are achieved.

Now it has emerged that United are unhappy with Brentford for their conduct during negotiations for the Cameroonian.

ESPN's Rob Dawson wrote: "Fair to say that Man United aren't thrilled with how Brentford handled the Mbeumo negotiation.

"View is that their valuation changed repeatedly and at one point it was as high as £70m + £7m.

"Also believe Brentford wanted Mbeumo to reject United in favour of Newcastle or Spurs."

Newcastle were reportedly interested in Mbeumo as they sought to add a right-sided attacker to their frontline.

After it became clear they would not get the player, they reignited their interest in Nottingham Forest's Anthony Elanga - who signed for £55m.

Thomas Frank was also interested in bringing his former player with him to Tottenham Hotspur, but Mbeumo had already decided to move to Manchester.

Spurs instead signed Mohammed Kudus from Premier League rivals West Ham for £55m.

They are also interested in Forest's Morgan Gibbs-White and made a £60m bid for the attacking midfielder.

Tensions have since grown between the clubs, with Forest executives shutting down communication and have threatening legal action over a supposed illegal approach.

What will Bryan Mbeumo add to Man Utd?

Most importantly, he should provide goals for a misfiring frontline.

He scored 20 Premier League goals last season, although he outperformed his xG and scored five penalties, so that is unlikely to be repeated.

Alongside Matheus Cunha, who scored 15 league goals, he will provide a welcome boost for Ruben Amorim.

Mbeumo is also one of the most creative attackers in the Premier League, with Yoane Wissa the main beneficiary at Brentford.

Only Mohamed Salah and Alexander Isak provided more goals and assists last year.

Mbeumo also fits in to INEOS's apparent strategy this summer of signing Premier League proven players in their prime years.

Although the fee may seem excessive, it may be a necessary price to give Amorim a fighting chance next season.

If United can also sign a striker, then United will have been rejuvenated their attack in one summer.
