As the Red Devils sit seven points clear on top of the Premier League table and find themselves in the Champions League Round of 16, you could excuse the players for wanting to focus on bigger fish but Smalling says winning the prestigious cup tournament is something they want to achieve.
"The manager has made the point to us that we have not done too well in the last few years," Smalling said ahead of the weekend’s third round trip to West Ham United.
"We need to make sure we get back on track in the competition.
"The league is going well and we're into the Champions League knockout stages, so we want to do well in this as well.
"The FA Cup has always been a massive competition.
"You've got the situation where lower league teams have the chance to play some of the top sides. It can be a real adventure."
