Carling Cup review:Javier Hernandez rode to Manchester United's rescue for the second time in three days when he scored a late winner to knock Wolverhampton Wanderers out of the Carling Cup at Old Trafford.
The Mexican camme off the bench to score the odd goal in five after United had twice surrendered their lead against Mick McCarthy's side.
After a lacklustre first half in which the understrength homeside appeared decidedly lethargic, summer signing Bebe gave them the lead when his cross deflected over Wayne Hennessey's head and crossed the line despite the best efforts of Republic of Ireland international Kevin Foley.
George Elokobi, however, headed the first equaliser when he nipped in ahead of United goalkeeper Ben Amos on the hour.
Ji-Sung Park restored United's lead 10 minutes later after keeping cool under pressure after Federico Macheda's shot was blocked.
It took Wolves just six minutes to level it up again, this time Foley showing the way with a drilled finish across Amos's goal after his international team-mate Darron Gibson was dispossessed by Sylvan Ebanks-Blake.
Gibson made amends, however, when he fed substitute Hernandez and the Mexican dummied his mark and fired a left-footed effort past Hennessey in the 90th minute.
