#5 Adam Lallana
With the arrivals of Fabinho and Naby Keita, and the expected signing of Nabil Fekir, Liverpool's midfield is now extremely strong in both quality and depth. The Reds have a host of midfielders who can feasibly start for them. One of the many options at Jurgen Klopp's disposal may be on his way out.
Jordan Henderson, James Milner and Gini Wijnaldum all played a huge part in taking Liverpool to the Champions League final. Alex Oxlade-Chamberlain has enjoyed an excellent first season at Liverpool, he already looks like a better player under Klopp than he ever was at Arsenal. That leaves Adam Lallana. Admittedly, he is one of Klopp's favourite players. But with the barrage of options at his disposal, he might be willing to let Lallana go.
The English midfielder signed from Southampton in 2014 but did not settle in immediately. It took a few years for Lallana to reach his full potential at Liverpool. After a great 2016-17 season, he suffered a hamstring injury before the start of the 2017-18 season. He, like Clyne, did not play enough games for Liverpool throughout the season. He also struggled in the Champions League final after coming on for Mo Salah and did not make England's 23-man squad for the 2018 World Cup.
He is the least likely on this list to leave Liverpool and probably won't, but it may be better for him and his career to do so.
