Giggs claims his old pal Solskjaer can build a new, exciting era - but fans and the board will have to be patient.
Giggs said: "Klopp wasn't brilliant overnight but I think what you've seen from him is improvement every year.
"It was a gradual improvement and I think, as a United fan, that's what you want to see.
"I'm not saying we're going to win the league this year but if you start seeing improvements and a shift of culture with players you want to go and watch...
"We're maybe not going to win every game but you will see players who want to play for the club."
