Over the past few season i think we have lost more important players than these 5 and have always come back stronger. If it is just those 5 i am sure we can improve on Pelle, Juamni and Tadic. Mane and Wanyama will be more difficult but i don't think it is that far fetched that we could find players to at least match their levels. Keep it to five and i am very excited for this summer and next season
