Ighalo doing what it says on the tin since joining man utd solskjaer

I think there may be some confusion here!

Odion Ighalo is a Nigerian professional footballer who plays as a striker, but he has never played for Manchester United under Ole Gunnar Solskjær. In fact, Ighalo joined Manchester United on a loan deal from Shanghai Shenhua in January 2020, and his loan expired at the end of the 2019-2020 season.

During his time at Manchester United, Ighalo scored 7 goals in 23 appearances, including a memorable winner against Norwich City in the Premier League. However, he has not played under Ole Gunnar Solskjær for the entire duration of his loan spell, as Solskjær was appointed as Manchester United's permanent manager in December 2018, about 6 months before Ighalo joined the club.

So, unfortunately, Ighalo hasn't been "doing what it says on the tin" under Solskjær, as he wasn't even at the club when Solskjær took over!
