Liverpool vs. Manchester United.
It’s probably the biggest fixture in the Premier League and it takes place tonight at Anfield.
The Reds head into the encounter as slight favourites after their impressive start to the campaign sees them three points ahead of their arch-rivals.
The Red Devils were early season favourites for the Premier League after winning their opening three league matches, but have since lost to Manchester City, Watford and drawn at home to Stoke.
It leaves Mourinho’s side six points off Manchester City and Arsenal at the top of the league going into the titanic clash.
While the clash may be a tough one to call for many people, there is one United legend that simply can’t see past a Liverpool win.
That man is Paul Scholes and he admits that, if he was a betting man, he’d be placing his money on Jurgen Klopp’s side tonight.
Scholes on United
"If you were betting, you would be betting on Liverpool," he said, per BBC Sport.
While it’s unlikely that the former midfielder will actually be placing a large wager on the Reds, he’s explained why he’s concerned for his former side at the moment.
"He was not ruthless enough in the off season. There is so much confusion about who should play.
"What I saw of Mourinho at Chelsea, he had 13 or 14 players who played every week. He never rested players even in the League Cup or whatever competition he was in.
"With United it is still a settling-in period - it is going to take a bit of time for them to knit together and see what they are about.
"Is there an identity to the team yet? I don't think there is."
Mourinho has already used 15 outfield players in their seven league matches and there is plenty of competition for places. While that may sound like a good thing for many bosses, the Special One is notorious for rarely changing his starting XI, represented by the fact he only used 21 players 2004-05 and 2005-06 title-winning campaigns with Chelsea. In 2014-15, when he won the league with the Blues for a third time, the figure was 19.
But it’s not just because he doubts United’s quality that he’s backing Liverpool tonight. He feels that Klopp’s side are in great form and believe they will pose a massive threat to United.
Scholes on Liverpool
"You can see Jurgen Klopp has stamped his way of playing football on the team," said the 41-year-old.
"There is a definite way about them. You know how they are going to play. They are going to be quick, they are going to try to take the ball off you and try to score goals by flooding the box.
"I was worried about them defensively - but they have already played some of the big teams and they are a real threat.
"The form they are in, they look as good as any team in the league."
