Cahill set to seal Red Bulls switch
"Tim will move to the Red Bulls for a nominal fee, subject to agreeing personal terms and passing a medical. He will travel to the U.S. in the next few days," Everton said on their website.
British media reported the transfer fee would be about one million pounds.
