Many of the world's football clubs are getting through busy periods, with domestic cup matches and European competitions vying for attention and sapping their energy. But there is still important work to do in league play. This weekend has plenty of competition in the top leagues, and bettors can get in on the action. The highlight is the Manchester derby in the English Premier League, as second-place Manchester City visits Old Trafford to take on fourth-place Man United on Saturday at 7:30 a.m. League leader Arsenal also faces a key match, visiting Tottenham in a top-five North London derby battle Sunday at 11.30 a.m.

There are plenty of other intriguing matches in Italy's Serie A, Spain's La Liga and France's Ligue 1, among many others. Manchester City are -121 favorites, with United +305 underdogs, in the latest soccer odds from Caesars Sportsbook. Arsenal are +114 favorites as they try to maintain (or increase) their five-point lead atop the table. (For complete soccer coverage and more expert picks, check out our soccer analysis pages) 

All these games offer many opportunities for bettors, and the paydays can be even bigger if you combine your favorite picks into a parlay. Before you make any soccer picks or parlays, you really have to see what soccer expert Jim Holliman has to say.

Holliman has been a writer and editor for nearly 25 years and grew up with soccer in his blood. He played competitively through high school and has been following the game closely since the 1970's heyday of the North American Soccer League. His interest has expanded worldwide, and his betting approach is centered on crunching the numbers, but he sees the whole field and relies on his instinct.

The expert is 5-1 (+409) on his Champions League picks and was 8-4 (+490) on his final 12 World Cup plays (5-0 on over/under picks). He also went 14-9-1 on picks in his world soccer parlay article over the six weeks before the World Cup break.

Holliman has scoured the soccer schedules for Jan. 14-15 and has found value in four best bets. If you combine these four picks into a parlay, you could earn a MASSIVE payout of almost 13-1 at Caesars Sportsbook! The first matchup in the parlay doesn't start until Saturday at 10:15 a.m. ET, so there is plenty of time for you to make your soccer picks.

We can tell you that one pick that Holliman loves is Arsenal vs. Tottenham Over 2.5 Goals (-130). These are two of the highest-scoring teams in the Premier League, and six of the past seven meetings have gone over 2.5 goals. Spurs will try to put on a show for the home fans, and that could leave them vulnerable against the league leaders. 

Holliman has three other picks in his parlay that would pay almost 13-1, including CONFIDENT plays on two more games he expects to be high-scoring affairs. If you combine these picks into the four-leg parlay, you can cash in HUGE! You ABSOLUTELY need to see the expert's predictions before you lock in any soccer picks or parlays of your own.
