The midfielder at the start of the season was sent on loan to the Dutch first division with VVV Venlo.
He struggled to get the required game time, as he played just nine of 19 games and found the back of the net just once.
However, his parent club decided to terminate the loan agreement and send him back to where he impressed while on loan in the 2016/17 season.
Kelechi is the younger brother of Manchester City's Chidiebere Nwakali by his parent club.
Kelechi who won the Golden ball at the 2015 U-17 World Cup, made 29 appearances and contributed two goals for MVV Maastricht last season, he is yet to feature for the Arsenal first team and Super Eagles.
