I doubt it's simply a case of not offering Wijnaldum a contract. He's at a difficult age to renew - he's going to want a 4 or 5 year deal on big money and while I'm sure the club have no issue paying a 29-31 year old Wijnaldum big money, they dont want to commit to paying a 33 or 34 year old Wijnaldum big money.
There is also a small side issue we have with the age of our midfield and attack. If you look at the first choice front 6 from last season of Fabinho, Wijnaldum, Henderson, Mane, Salah and Firmino, with the exception of Fabinho, they're all aged between 28 and 30. You don't want too many players getting old at the same time and if there is any truth in the Thiago stories then you could end up with 6 big earners and key players all in that age bracket. Whatever happens I just hope he stays this (summer unless a big offer comes in) and maybe that's the best for all concerned - we get another peak year out of him on relatively low wages and he gets his pay day in the summer.
As for the Chelsea chat above. They've signed some good players and very promising players but a little perspective is needed. Neither Havertz or Werner start for Liverpool or City and Chilwell isn't getting in our side ahead of Robertson either and they still have a pretty poor back line and terrible keeper.
