Donovan admits he'd welcome a return to Goodison Park for a third time.
"Itâs reiterated to me that I can play not one game, not two games, not three games at that level, not a World Cup tournament at that level, but that I can consistently play at that level over eight, 10, 12 games,â he explained to evertonfc.com.
"And, being there I have so much respect now for guys that play 30, 35, 40 games in a season and are consistently good, because itâs so demanding physically and mentally. Itâs really draining and itâs very demanding. Guys that are able to do that have all my respect."
