Watch: Zenit's Aleksandr Kokorin misses an open goal from two-yards out

Roberto Mancini's Zenit played out a goalless draw against Terek on Monday night, but it could have been so different had Kokorin converted from a matter of metres out in front of an open goal.In the 57th minute, Emiliano Rigoni attempted to lob Terek goalkeeper Vitaliy Gudiev from a tight angle, but his effort bounced off the bar and into the feet of Kokorin.Yet somehow, the 26-year-old failed to even hit the target with his effort and really should have broken the deadlock.Unbelievable.With the Russian Premier League tie finishing a point apiece,Lokomotiv Moscow are now eight points clear at the top of the table after 20 games played.SEE ALSO...Watch: Chennai goalkeeper's dreadful, lazy clearance produces inevitable results​Watch: Cardiff's Callum Paterson scores woeful own goal against ReadingIn Other News... on FourFourTwo.com​
