They had been after him all window but Palace held firm. Unfortunately though he wasn't their number one priority, Isak was.
It was a very odd window for them when you look at it. They bought a player Newcastle wanted in Ekitike - had they not done this, the Isak transfer may have gone through sooner.
They sold a very solid performer in Diaz.
Continued in their quest for Isak, knowing they won't be playing two up top, rendering the Ekitike signing useless.
Palace told them to F off at the last minute for Guhehi. I think they believed this move would go ahead, no matter what. Hence why they just kept toying with Palace.
