Tehran: Persepolis were left to rue missed chances after a 0-0 draw with Al Rayyan in AFC Champions League Group D on Monday. Striker Mehdi Taremi squandered the game’s best opportunity on the stroke of half-time, lofting a chipped penalty over the bar following a foul by Al Rayyan left-back Mosaab Kheder. Fellow forward Ali Alipour, meanwhile, had a fine headed opportunity to give Persepolis a lead with just 10 minutes on the clock but was unable to control his effort at goal. The misses almost proved costly when Al Rayyan's Sebastian Soria rattled the post with the game already deep into injury time following a flowing counter-attacking move. In the end, though, neither side were able to claim all three points and Group D remains in the balance with two rounds of fixtures remaining.
