Manchester United defender Chris Smalling says their clash with Bayern Munich is a must-win.

Smalling is hoping Manchester United can end pre-season in a positive manner and then set a marker in the Premier League season opener with Leicester City.

“I think it [the start of the season] does come round very quickly," he admitted to MUTV, “But that's Manchester United.

“We're often the most talked about, and why not let us set the tone for the season and hopefully just get that win and set a marker?"

The defender is gearing up for his ninth season at Old Trafford, meaning he is one of the most experienced members of Jose Mourinho's squad.

“It does feel like I've been here quite a few years but it doesn't feel that many," he admitted, when reviewing his time with the club.

“It's crazy, if you sit down and think about where it all started and certain games and how the process has gone, it's pretty crazy."
