Mikel Arteta is open about the move from Chido Obi to Manchester United, while the former Arsenal Academy star is introduced for the first time to face his old side.
The 17-year-old completed a surprise movement to Old Trafford in October and has since had opportunities for the first team in the midst of the recent injury of United.
His recent cameo against Fulham received the supporters of Red Devils puring and they could still get a glimpse of the young person when they act against Arsenal.
Prior to the game, Arteta admitted that it was 'a pity' that OBI decided to leave, but insisted that the Gunners 'continued' from his departure.
“It is clear that when a player decides that the best path is for him to leave, there is not much that you can do,” explains the Spaniard.
'Very unfortunate because we want to keep our players from the academy and be very successful with the first team. But in that case, with Ayden (heaven), we couldn't do that.
'To convince a player to stay a player, must be willing to be with us and to commit to us and I don't know specifically, both parties will feel very different about it.
“The reality is that he has decided to move and we went further.”
Asked about the qualities of the 17-year-old, he said: “” Solid threat, an attitude and love to be in the box and a capacity to score in many different ways. He was. '
At the beginning of the month, after the Youth Cup victory of United on the Gunners, OBI aimed a thinly horny count on his earlier side.
The Red Devils claimed a 3-2 victory after extra time at the Emirates to book their place in the semi-final.
Replacement Bendito Mantato decided the game with a 99th minute strike and then posted on Instagram: 'Until the end, my team, in the Halfis'.
Obi-Martin, who left Arsenal for United in October and then noted 'thank you so much', with different smiling emojis.
The 17-year-old striker was not involved in the quarterfinals collision, because he was promoted to Ruben Amorim's first team after the seasonal injury of Amad Diallo last month.
He got his debut away from Tottenham and also got first team minutes in the 2-2 draw to Everton last week.
OBI has been a revelation this season for young people under the age of 18 in the Youth Cup and scored seven goals in the three games of United prior to the victory over Arsenal.
