For a winger who has recorded 23 appearances with just a goal and three assists are you sure this is the player Manchester United which is currently struggling needs? With the current situation I think united should be looking at very good players who can immediately make good impact as they join and for a fee not too expensive to give room to sign more. They need wingers who can guarantee atleast between 10 to 15 goals in 23 appearances.
Yes, I think Man Utd need a mature player as soon as possible to get out of the pressure, not a young player like Geovany Quenda who is still developing his ability, Man Utd is not a team that can really manage young players, only a few succeed and others fail. And considering the English league is very competitive, Quenda is not strong enough to lift the performance of The Red Devils in the near future.
For the option of adding depth to the squad it might be good, but to be a regular player I am quite doubtful.
Before they can sign a young player like Geovany Quenda, it will be at a time when the club has attained some level of stability in the squad and not now they are still struggling to build up the team. They need players that are full of life and strength to be able to carry the team to a good position they won't be facing many setbacks again. Manchester United is in a stage of making sure they develop the team so they don't need young players for now until Amorim is able to revive the team again and they become competitive like other top England teams.
