Chris Smalling believes that Yeovil Town will provide his Manchester United side with a "tough battle" when they meet in the third round of the FA Cup this afternoon.

With United battling at the top end of the Premier League and Yeovil bottom of League One, many expect Louis van Gaal's men to run out comfortable winners at Huish Park.

However, centre-back Smalling has insisted that United must do a "professional job" to ensure that they progress through to round four of the competition.

"We'd have obviously liked to have been drawn at home. It will be a tough battle there with Yeovil having nothing to lose," he told the club's official website.

"We have to make sure that we go there, do a professional job and show our class."

United have faced Yeovil on two previous occasions in 1938 and 1949, scoring a total of 11 goals and conceding none.
