If you ever have a chance to meet Haris Medunjanin, you should take it. Just say hello, exchange a few words, see how the 33-year old Bosnian carries himself and treats those around him. Medunjanin, who is probably still best described — with the phrase Earnie Stewart may have brought to the American soccer lexicon — as a controlling midfielder, embodies the intense work ethic, team-first attitude, and veteran leadership Philadelphia Union felt they needed in the center of the park. And now he is sticking around for another year after signing a contract extension the club announced on Thursday.
