Wouldn't be surprised if he was a Players Association member, but that's besides the point.
I'd rather have him average 70ish minutes a game and score goals like a beast instead of playing the full 90 and just being worn out all of the time.
This just comes back to the original point, that yes getting another striker more reliable than Jelavic should be a priority. Even if it's a 4th loan that just amounts to a short-term Kone replacement.
Jelavic has served us well but I think it's time for him. Back to Scotland, Austria, or a league of similar caliber where he can get more regular playing time and secure his World Cup roster spot.
