Manchester United manager Ole Gunnar Solskjaer was heavily criticized by many when he sanctioned a deadline day move for Nigerian striker Odion in January.
However, months down the line, the manager has been vindicated for his shrewd choice.
On Saturday, Ighalo making his fourth start for United netted his fifth goal; helping the Red Devils reach the FA Cup semi-finals for the third time in five seasons.
Solskjaer reserved praise for Ighalo after another good show even as he described him as a proven goalscorer
Loanee Ighalo now has five goals in four United starts and his loan extension allowed Solskjaer to rest Anthony Martial, who came on in extra-time as United went to two up front after Norwich defender Timm Klose was sent off.
“It’s great to have the option to rotate,” Solskjaer told the BBC. “Anthony has done really well, Anthony came on and did brilliant, created chances. But Odion gives me a chance to rest Antho and is a proven goalscorer.
“And today he has played a part in both goals and is great to have around the dressing room.”
Solskjaer played almost exactly the same side that beat Derby County in the FA Cup fifth round 116 days earlier and the eight changes affected United’s flat performance at Carrow Road.
Solskjaer accepted the rotation had compromised United’s fluidity.
