The summer buy from Manchester United says his new club needs to produce the same kind of consistency that has become the hallmark of his previous employers.
"The most successful teams are also the most consistent," O'Shea told The Journal. "It hasn't happened for us yet, but that's what I'm looking to happen here soon because that's what's going to see us climb into the top half of the table and stay there.
"When we beat Stoke City 4-0 recently I was pleased but I was already looking towards the Norwich game a few days later.
"It's safe to say that I was more disappointed at losing to Norwich than I was pleased to have beaten Stoke - and one of the main reasons for that is because you need to string together results to get momentum."
