It could come down to motivation Sunday when relegation-threatened Celta Vigo host league champion Barcelona in a Spanish La Liga season finale. Barcelona (28-4-5) clinched the league title three weeks ago, but they come off a 3-0 dismantling of Mallorca last Sunday after a couple of sluggish outings. Celta Vigo (10-10-17) are 17th in La Liga's table, even with Almeria on 40 points and one ahead of 18th-place Vallodolid. Three other teams have 41 points, two points clear of the drop zone, so gaining points will be crucial on the season's final day. Celta Vigo are 0-1-5 in their past six matches, including a 1-0 loss to Cadiz last Sunday.         

Kickoff at Estadio de Balaidos in Vigo, Spain is set for 3 p.m. ET. Caesars Sportsbook lists Celta Vigo as slight +155 favorites (risk $100 to win $155) on the 90-minute money line in its latest Celta Vigo vs. Barcelona odds.

Why you should back Barcelona

The visitors appear to have shaken off the celebration hangover, as they were simply dominant last week. Barcelona held 79% possession and outshot Mallorca 28-3, putting nine shots on target and conceding one. Ansu Fati got a rare start, and the 20-year-old made the most of it, scoring two goals. That gave him seven for the season, in 12 starts. Gavi also scored, and he and fellow midfielder Raphinha gave Celta a lot of trouble in the first meeting in October. Barcelona won that meeting 1-0.

Striker Robert Lewandowski, the league's leading scorer with 23 goals, should have an impact. Mainstays Sergio Busquets and Jordi Alba will be making their final Barcelona appearances, so the team will want to send them out with a victory. The hosts will have to work for goals Sunday, as Barcelona have the league's best defense. Marc-Andre ter Stegen has 26 clean sheets, 11 more than any other La Liga keeper, and they have yielded 18 goals in 37 games. See who to back at SportsLine

Why you should back Celta Vigo

The hosts are 3-3-1 in the past seven meetings between these teams at Estadio de Balaidos. Barca haven't won both league meetings in the same season since 2013-14. And with the home crowd behind Los Celestes and their spot in the top flight on the line, they will be much more motivated. They had a 14-13 edge in shots and had plenty of chances to score in the first meeting. Captain Iago Aspas failed to beat ter Stegen one-on-one, and Gonzalo Paciencia drilled the post late in the match. Celta have 151 shots on net, eighth-most in the league.

Aspas, who has double-digit goals in all eight seasons with Celta and has 12 in this campaign, will be the key for the hosts. Young midfielder Gabriel Veiga has nine goals, and six other players have scored at least twice. Barcelona were outscored 5-2 in losing consecutive matches after clinching the title. That included a 3-1 setback to Valladolid two weeks ago that helped put Celta in peril. The hosts harass whoever has the ball, especially between the attacking areas. They have the fourth-most tackles in the league, second-most in the middle third of the pitch. See who to back at SportsLine
