The main interest for football punters on the final day of Christmas week is the two Premier League contests – Sunderland host Leeds United at 2pm, before Crystal Palace welcome Tottenham Hotspur to Selhurst Park for a 4.30pm London derby.Alternative betting opportunities for football fans come in the shape of four African Cup of Nations group matches, as well as four Serie A fixtures from Italy.BET £10 AND GET A £50 FREE BET WITH talkSPORT BETSunday football betting tipsSunderland v Leeds United draw @ 85/40The first Premier League match of the day looks set to be a serious scrap between Sunderland and Leeds United – two well supported northern clubs who could be set to play out a tight, tetchy 90 minutes.Sunderland are unbeaten at home this season, conceding just seven goals in eight games, but there are reasons for believing Leeds can grind a point from the Stadium of Light.Daniel Farke has eased some of the pressure on his shoulders in recent weeks, tinkering with his formation and taking Leeds on a four-match unbeaten run. A 3-1 victory over Chelsea at Elland Road was followed by a 3-3 draw with Liverpool, a 1-1 draw at Brentford and a 4-1 thrashing of Crystal Palace.Suddenly, Leeds have eased clear of the relegation zone, and they can further bolster their chances of staying up by taking a point from Sunderland. The Black Cats have lost six players to the African Cup of Nations, which accounts for a fifth of the Premier League representatives at that competition.Sunderland have enjoyed an incredible start to the season, but the AFCON has taken players who have made a total of 61 Premier League appearances this season. The weakened Black Cats may have to settle for a point. Bet builderCrystal Palace v Tottenham Hotspur – Draw and under 2.5 goals @ 31/10An intense atmosphere can be expected for the London derby at Selhurst Park on Sunday and a closely-fought contest seems on the cards.Palace have recorded seven clean sheets in their 17 Premier League outings this season and that defensive solidity stands them in good stead for repelling Tottenham. Oliver Glasner’s side are a tough nut to crack at their Selhurst fortress.Glasner prefers a counter-attacking style, so expect Tottenham to have the ball for long periods. Heavy Spurs possession and a well-drilled, defensive home side could lead to a low-scoring game.Backing the draw, plus under 2.5 goals, is the most appealing Bet Builder option of the day.AccaSunderland v Leeds draw (85/40), Crystal Palace v Tottenham draw (23/10), AC Milan to beat Hellas Verona (4/11) @ 13/1The two Premier League matches of Sunday look set to be close – and it is entirely feasible that they both end in a draw. Putting two draws in a treble with the most likely Serie A winners of the day – AC Milan – pays to a whopping 13/1.Milan have lost only one league game all season and are 20 points ahead of their opponents, who have only two of their opening 15 games in Serie A and find themselves in a relegation dogfight.BET £10 AND GET A £50 FREE BET WITH talkSPORT BETOdds correct at time of publish and subject to change*T&Cs: 18+ New Customers.
