Manchester United disappointed a lot by their worst performance in this UCL season. As they threw out of UEFA Champions League from the group stage only. Nowadays they had did a comeback in English Premier League.
As they stood in 3rd position in the English league and trail by 5 points from table topper Liverpool. Ole Gunnar Solksjaer failed to bring new players during the last summer transfer window and brought Cavani on the last day via free agent transfer.
Before then, he introduced Facundo Pellistri the Uruguayan footballer who is only 18 years old. Recently, he joined the U23 Manchester United side for his proper development in skills and physical strength.
Likewise, Ole Gunnar Solksjaer played the same move by having a deal with an Ivorian winger. As he closed the deal by signing him on £22.6m along with £13.6m bonuses. In the end, Amad Diallo becomes the highest-paid teenager till now.

According to a report from Fabrizio Romano’s The Guardian
Will arrive in the late January
The Times report claims, “He and United have now applied for a Governing Body Endorsement (GBE) certificate from the FA.If, as expected, Diallo is given a GBE he will then apply for a work permit from the Home Office, which is likely to be granted.”
The further report also cleared that there are no expectations that he will arrive on 1st January. But hope to come in the last week of January. He will directly join the squad without attending the quarantine period. As he already in the elite sports bubble in the Atalanta.

Till then Ivorian winger most of the time remain on the bench for this season as he had appeared in only five matches. In these five matches, he netted once and played only a couple of minutes for the first team of the Atalanta.
Advantages of signing Atalanta winger
Amad Diallo plays at Left-wing, Right-wing, and attacking midfield position. So it will help Ole Gunnar Solksjaer to strengthen his midfield. If he gets a chance in the first team then it will help Bruno Fernandes.
His speed and quick skills will help Manchester United to make their attack fast. Therefore, Cavani, Bruno, Rashford, and Amad Diallo will bring brilliant attacking gameplay for the Old Trafford side. Further, they will get the support of younger Facundo Pellistri in upcoming years.
Will Amad Diallo get chance directly in playing eleven?
Recently, Ole Gunnar Solksjaer had found the perfect attack for his team with new arrivals in the summer transfer window. So cementing a place directly in the first team is quite difficult for Amad Diallo in front of senior players.
Henceforth, Amad Diallo might play in the U23 squad of Manchester United alongside of Facundo Pellistri. Both of them might do their debut at the start of the next season. Hence, Ole Gunnar building the step by step young squad for the next season.
