Odion Ighalo admits Nwanko Kanu was in contact after signing for Manchester United.

The former Arsenal star has been urging Ighalo to reverse his Nigeria international retirement.

"He sent me congratulatory messages when I signed for Manchester United," Ighalo said.

“He advised me to keep working hard and I'm going to surprise so many people that didn't give me the benefit of doubt of coming to that team, that he sees me doing well there, that I should work hard and believe in myself and I should not let talk of people distract me."
