John O'Shea says it's time for Manchester United to end their German Champions League hoodoo against Schalke.
After failing to overcome Borussia Dortmund at the same stage in 1997 and Bayer Leverkusen two years later, the Irishman feels it is time United flexed their muscle.
"We have to make sure we show them our history, why we have got to finals, why we have won them, why we have been in this situation many times before," he said.
"We have to impose ourselves whilst understanding the threats they have, which we will have to cope with."
