Naby Keita is on his way to Werder Bremen on a free transfer. I'm afraid Keita couldn't show the expected performance for Liverpool most of the time. He has never been a regular in the starting eleven also. I don't remember him playing like in nearly all games in a season. I think this is the right choice for Liverpool and it seems like they are doing some cleaning in the midfield also.
I mean together with Keita there are 3 more midfielders who are about to leave the team this summer. Oxlade and Milner are going to be released and Arthur's loan time is also ending at the end of the month. They are making the moves to strengthen the midfield on one hand. Alexis Mac Allister is joining the team by July 1. This is really important for Liverpool because I think that the midfield has been the weakest point of the lineup so far.
All three players have lost their place in Jurgen Klopp's starting eleven. It's been a really tough and rough season for Liverpool, I barely exercise them to qualify for any European competition next season but somehow they managed to get back their momentum and pull back vital points to move up to top 6. With these players leaving, Klopp will have to replace them with young and better players who will improve the squad for the coming season. Mac Allister already joined in the week, I believe we will be seeing more additions to the Liverpool side.
