Let me say a few thing that could make you think otherwise for Mbuemo.
Mbuemo is an right wing attacker, tested and proven in the EPL, clinical finish if he plays in a club that create opportunities, he has strength and like you said an attacker.. not a striker that will give you almost 20 goals in a season. Manchester United almost went to relegation last season, look at their strengthen no big player will want to come to the club, so I dont know what you expect a world class player. Do you know how much a club will demand if a world class player agrees to move to Manchester United? What they need is exactly current EPL players that can push them up in the table next season, not one they are testing.
I don't know why people keeping thinking that a club must sign big players before they'll succeed, I love your reply to his statement, so because Manchester United has Amad they shouldn't increase their depth? United's problem last season was lack of goals, they began playing good football after a while when Amorim came in but the attackers couldn't often find the net which caused a big issue last season, now they've signed Cunha and are about to sign Mbeumo and both players g/a is more than 40 or close to if am not mistaken yet people are still complaining, who said Manchester United won't sign a top 9 after Mbeumo? Also I think they're forgetting than Amad has been used in the right wing-back under Amorim and he excelled in that position. Imagine Cunha, Mbeumo, Bruno, Amad and a good 9 in the starting 11, that's a huge upgrade.
This is the exact same thing people thought when they Antony was signed Antony. Antony is an average player who was bought at the price of a world class player.
First of all, let me address the "proven in the EPL" talk. It doesn't matter if a player has been playing in the EPL for 7 years, if he moves to an environment that is not good, he will struggle.
don't also forget the fact that there are players who do very well in a small team but struggle in the a big team. The fact that a player was good in Brentford doesn't mean he will be better in United.
I never said United shouldn't sign Mbuemo or they shouldn't sign another player because they have Amad, my point was allowing teams strong arm them into signing an average player for an expensive fee. You can't keep buying players that are not worth it for a high fee and complain when they don't deliver like world class players. 60 million Euros for Mbuemo is enough and United shouldn't be offering more than that, they should know hoe to make better deals.
