Keita arrived at Anfield in the summer of 2018 from Bundesliga side RB Leipzig. Despite being at the club for five seasons, the Guinea international has only made 129 appearances across all competitions and has contributed just 11 goals and seven assists.The 2022-23 season has been no different for Naby Keita with injuries keeping him out for the majority of the time. He has played just eight times for Liverpool this season, with his last Premier League appearance coming all the way back in February.Oxlade-Chamberlain, on the other hand, arrived at the club a season before Naby Keita did. The former England international had a decent start to life as a Liverpool player with a few memorable performances. He scored a great goal from outside the box against Manchester City in the UEFA Champions League quarterfinal back in 2018. Injuries have since limited his game time at the club.In his six seasons on Merseyside, Alex Oxlade-Chamberlain has made just 146 appearances across competitions. He did contribute 18 goals and 15 assists long the way. The current season, however, follows a similar trend to that of Naby Keita's. Oxlade-Chamberlain has played just 13 games this season in all competitions. He did score a goal against Brentford back in January. Liverpool went on to lose that game 3-1.Naby Keita and Oxlade-Chamberlain were part of a successful Liverpool team under Jurgen KloppDespite their troubles with injuries, both Alex Oxlade-Chamberlain and Naby Keita were part of a successful era at Liverpool under the management of Jurgen Klopp.The midfield duo were part of the squad which lifted numerous trophies, including the UEFA Champions League in 2019 and the Premier League title a year later.The pair also went to win other accolades, including the UEFA Super Cup, FIFA Club World Cup during the 2019-20 campaign and the FA Cup the previous season.
