Barcelona kicks off its 2022-23 Spanish LaLiga season with a home game Saturday against Rayo Vallecano. Barca fans are hoping to be able to cheer a slew of new players, including superstar Robert Lewandowski, who came over after eight seasons with Bundesliga power Bayern Munich. The 33-year-old Polish striker is among the players who have not been able to register with the league because of its financial rules. Barcelona finished second to Real Madrid last season and has won the league title 26 times but not since 2018-19. Rayo Vallecano finished 12th in La Liga's table but beat Barcelona 1-0 in both meetings last season.          

Kickoff is set for 3 p.m. ET at Camp Nou in Barcelona, Spain. The latest Barcelona vs. Rayo Vallecano odds from Caesars Sportsbook list Barcelona as the -440 favorite (risk $440 to win $100). Rayo Vallecano is a +1300 underdog, a 90-minute draw is priced at +500 and the over/under for total goals scored is 3.5. 

Before you make your picks or predictions on the Rayo Vallecano vs. Barcelona matchup, you NEED to see what soccer insider Jon Eimer has to say.

Eimer is a high-volume bettor who has vast knowledge of leagues and players across the globe. Since joining SportsLine, Eimer has covered the English Premier League, Serie A, the FA Cup and much more. He is 204-187-7 on his SportsLine picks in 2022, which includes a run of 51-34-1 on his last 86 picks (59.3 percent) for a profit of more than $900 for $100 bettors.

Eimer knows that Barcelona remains one of the top teams in the world and just added one of its most lethal strikers. Lewandowski scored 110 league goals over the past three seasons at Bayern, and he could still be cleared to play. Rapinha also was added to the attack, and he had 17 goals and 12 assists over the past two seasons with Leeds. Barca also still has the veteran leadership of midfielder Sergio Busquets and defender Jordi Alba. Memphis Depay and Pierre-Emerick Aubameyang are more than capable of leading the attack.

The expert also has considered that Los Franjirrojos put on a very strong performance in their first season back in the Primera Division last year. They finished 12th but started 9-3-6 before a 13-game winless streak brought reality home. But the two victories against the Blaugranes last season certainly instilled some confidence, and the uncertain state of the host club could provide an opportunity. Rayo Vallecano lost just once in its six preseason matches, which included a 0-0 road draw against Manchester United on July 31.
