New York Red Bulls signing Cahill open to Everton loan return
He said: "I'm totally focusing on the Red Bulls - getting fit, giving everything I can for the next three to four months.
"If something can work and fit to the training regime, because I've committed my future to the Red Bulls, and going on loan might not be the right thing for the football club... But if it works out that I can find the right happy medium to get the fitness and keep training and to play in certain games, then maybe yes.
"But I really think in the next three of four months we'll be able to tell closer to the end of the season."
