The focus on fixing the front line has been very good for Manchester United, but they also need to think about the defense because last season we saw that Manchester United conceded quite a lot of goals.
I just read that Brentford has rejected Manchester United's second offer. The initial offer was £55 million and the second offer of £62.5 million has now been rejected. It seems that Brentford is indeed doing this to get more money. Another news is that Mbeumo is known to be interested in Spurs because of Thomas Frank. He is Mbeumo's former manager. I think Manchester United is very eager to get Mbeumo because his statistics are very good; he is only behind Moh Salah.
