It appears that Mbeumo is eager to join Manchester United, but his transfer talks with the club have stalled due to a disagreement over the transfer fee with his current team, Brentford.
According to Besong, Mbeumo is feeling frustrated about the delay in the talks, but he remains calm and professional about the situation.
When Besong spoke to Mbeumo about a week ago, the striker seemed to be in a positive state of mind, despite the uncertainty surrounding his future.
Mbeumo has expressed his desire to join Manchester United and is grateful for the opportunities he has received during his time at Brentford.
However, the transfer fee has become a major hurdle in the talks, with Manchester United's initial offers of £55m and £60m being rejected by Brentford.
As a result, Mbeumo's price has increased to £68m, making the transfer even more challenging.
