You don't pass up on players like Götze when they're available, especially at the quoted fee of £18m-£20m. What if Coutinho leaves this summer or next? We'd shoot ourselves in the foot if we won't go for him. We have more pressing needs, yes, but which ones? A goalkeeper (already made contact with Barcelona for ter Stegen apparently, and it's not like goalies are that expensive anyway), left-back (interested in Jonas Hector which wouldn't be that expensive either) and a CM (interested in Piotr Zielinski from Udinese who is currently on loan at Empoli)... But with Can seemingly being an automatic starter under Klopp and Grujic coming back in, we'd have enough cover with Henderson and even Milner if necessary.
ter Stegen; Clyne/Flanagan, Matip, Sakho/Lovren, Hector/Moreno; Can, Henderson/Grujic/Milner; Firmino, Coutinho, Götze; Sturridge.
I'd be very happy with that starting XI going into next season (jumping the gun of course). Ibe, Ings, Origi, Lallana, Markovic is enough attacking talent to replace anyone. And it's not like we won't have anything else to spend even if we buy Götze at let's say £25m. I'd imagine Klopp will be given enough money to put together his own team and let's see how he takes it from there.
