United kick-off their pre-season tour with a friendly against Steve Nicol's men at the Gillette Stadium on 13 July and Joseph can't wait to come up against a side he sees as awe-inspiring.
"The technical ability they have is incredible. You have your mouth wide open when you see how good they are and how well they hold on to the ball, "Joseph told the official matchday programme.
"They are so good with the ball and keeping possession - I will have to keep my head on a swivel!
"It's likely they will try to control possession and we need to be ready to counter-attack.
"We will have to step up the tempo and take it to them when we can."
