Former Manchester United defender Fabio is happy seeing Solskjaer back at Old Trafford.
He told the Daily Mail: "I think that's the big difference, you know.
"The talent was still in these clubs but they didn't have the commitment or the work rate.
"At Cardiff I worked for Ole Gunnar Solskjaer. I love Ole. He had been reserve manager for me at United. He is a nice guy and I hated it because I felt some players took advantage of that.
"Me and my brother (Rafael) always had a desire but also we learned a lot from Cristiano and Fletcher, Carrick, Patrice. They each did it differently but they all worked so hard.
"I achieved quite a few things but I didn't do more because - I won't say I was weak - but I was not brave enough. I never played free.
"My brother was different. He went for the shirt. But maybe I never felt I was really equal to the others."
