I think this is a great deal for both parties. Tosun is a £15 million striker on form easily and palace are the ideal team for him. He is a very good finisher unfortunately just doesn't suit our style.
Mcarthey with a bit of luck with injuries for once in his career is a top midfield player of his type so £8 million is wort a punt Imo. £55 million is reasonable for a player of Zaha's ability in this crazy age, we get 2 players off the wage bill and use monies from sales to offset the cost.
Does Zaha improve us... absolutely all the haters slating him have made me laugh, he's proven in the premiership, he's reached his potential and would be devastating on the flank for us, he would probably be the most exciting player since kanchelskis.
Everyone is entitled to an opinion but why the hangup on the cost, it's not our money just be happy the club are having a go. Name a better or as exciting winger with premier league proven ability we could even dream of signing and I might agree with you, did someone mention Ryan fraser on here recently (good god). Peace.
