Arne this season did a very good job at Feyenoord which might be a consideration that he could be a good replacement for Klopp but honestly for this time as long as I haven't seen him at Liverpool I am still quite doubtful about his abilities.
Honestly I rarely see the Eredivisie except for a few matches and indeed a good situation in the Eredivisie does not necessarily end well in the EPL because the competition is still quite different in terms of quality but indeed when Liverpool have made their choice then we only need to see if Arne can really be the answer for Liverpool next season.

In addition, talking about the coach, it is certain that this will also not be separated from the news of Salah because if I remember correctly Salah allows extending the contract if his position is guaranteed and he must know who his future coach is. Now the future coach has been answered for Liverpool. the question is whether Salah will continue to extend the contract or look for new club options where he is also still in demand by clubs in the SPL.
