#2 Luis Suarez

Despite being 31-year-old, Luis Suarez is showing no signs of decline and is still an important part of Barcelona's first-team set-up.
The Uruguayan international enjoyed a stellar 2017-18 season and helped the Los Blancos win the La Liga title along with Copa del Rey and Supercopa de Espana. The former Liverpool superstar scored 25 league goals last season and finished behind Lionel Messi and Cristiano Ronaldo as La Liga's top goalscorer. Suarez also registered 12 assists in the league season, which was the joint-most in the La Liga, alongside Lionel Messi and Pablo Fornals.
Suarez started impressively this season as well and registered 11 goals and fours assists in 15 La Liga games. He also enjoyed a decent FIFA World Cup 2018 campaign with Uruguay and scored two goals in his team's run to the Quarter-Finals of the tournament.
Barcelona was recently linked with a number of strikers to replace the Uruguayan, however, he still got a lot more left in his tank and could restrain the Blaugrana from signing his replacement for few more years.
