Players get bought and sold by all clubs, it happens. Deal with it!
Players often want to move on from clubs and when they’ve made their mind up there’s little more you can do but to extract the maximum fee possible eg Isak.
Liverpool sold Coutinho for a huge amount and reinvested it into a world class keeper and centre back which moved them on.
When we sold Bale we bought more misses than hits.
Where we have been poor recently is recruitment where we have spunked huge amounts on mediocre players.
