The Eagles closed out a difficult week with a far less eventful goalless draw against Everton, the side that Zaha had tried to force a move to with a transfer request last week.
“It is part and parcel of football now," McArthur said of Zaha's situation. “At the time he felt that he wanted to go but I must say his attitude has been amazing since he has come back.
“He has accepted it and is fully committed to the squad, the team and the fans — look at the reception [they gave him], they appreciate everything he has done for this club. He is a brilliant lad.
“Keeping Wilf was massive for the club, the signings we have made are going to aid the squad, too, and make us much stronger. I think it has been a great window, the club have done great business which should help us push on."
