Seems fishy that he wasn't willing to join a Spanish coach at a London-based team which has continuity compared to previous years, but does want to join Liverpool without Klopp, surrounded with quite a bit more uncertainty at the moment.He is a very good player and perfect for you at the base of the midfield with MacAllister and Szobo on either side. He is a very neat and tiddy #6 with a good passing range and calmness on the ball that good players possess.
The reports earlier when Arsenal were interested suggested that the player didn't want to leave Spain. Seems like things have a changes and he is not averse to joining you guys.
I know fans like to go "oh he didn't want to move when it was Arsenal but he cannot refuse a club as big as ours when we come calling" but that's not how players think nowadays, so wonder what might have changed his mind if he actually joins us in the end.
