Manchester United utility man John O'Shea believes another win over Liverpool at Anfield could boost the rest of their Premier League campaign.
The Red Devils are currently one point behind leaders Arsenal in the title race, although the top of the table could be reshaped this weekend in Grand Slam Sunday.
O'Shea is determined to help maintain United's impressive recent record at Anfield before putting his feet up and watching Chelsea's mouth-watering trip to Arsenal.
With a busy festive fixture period on the horizon, O'Shea knows it is important to get a result on Sunday that could prove vital in the title race come next May.
"If you get a major result in one of the big games, it can have a massive effect on your season," said O'Shea.
"The points gap between the top four is not very wide, so the way it is building up, it could be an important weekend.
"Obviously, there are a lot more twists and turns to come but going into the busy Christmas period, it would give us a major lift to get a win.
"It would be nice to think we can get three points and then relax and watch the other game.
"That is why we have to be very focused on getting three points. If we play to our maximum, we can get them."
O'Shea's injury-time strike separated the sides last season, although the Republic of Ireland ace is not expecting another fairytale ending this time around.
"It was a very special moment," he said. "The goal was amazing enough in the first place but because it was late in the season and we were pushing for the league, it just added to the feeling.
"It was one of those things I will cherish because it might not happen again for a long time.
"My first thought was to get the ball in the net because I knew I would get hammered by the rest of the lads if I missed. After that, I just wanted to get away from the Kop and down to the other end of the field as quickly as possible."
