The Doncaster chairman saw his team lose 3-1 to City in a friendly on Saturday and is convinced the good times are just around the corner at Eastlands now the Swede is in charge.
Ryan said: "I feel under Sven they are in for a great season. I think they will finish comfortably in the top half of the Premier League. That will pave the way for a major challenge the season after for honours and Europe. The city of Manchester needs two top clubs."
