The Reds go into the international break on a high following Sunday's terrific triumph against Arsenal but are not at home again until 4 December when David Moyes' former club Everton visit Old Trafford. Before then, the fixture list has thrown up trips to Cardiff City, Bayer Leverkusen and Tottenham.
Smalling excelled at right-back from the outset at the weekend and made one vital tackle to halt Olivier Giroud when an equaliser looked on the cards. With Rafael injured, he will aim to continue impressing his manager in the role.
"It was a massive win for us as it really laid down a marker," Smalling told ManUtd.com. "I'm just glad we showed that determination to get the three points. We were under pressure, especially in the last 20 or 30 minutes, because we really did press them in the first half and didn't give them any room. In the second half, we maybe did drop off a little bit and they caused a few problems but we stood firm.
"We defended as a whole team. We worked on pressing the wingers and strikers because, if you let a team like Arsenal start to play, they have got such gifted players. There were a few dangerous crosses towards the end but, overall, it was pretty good. I had my heart in my mouth a few times towards the end but it’s nice to dig in and keep a really good clean sheet.
