#5 Jordi Alba 8.5 /10

Jordi Alba is one of the best fullbacks in the world at the moment. The left-back made 43 appearances and was spectacular with his performances. He scored 3 goals and assisted 8 more for the Blaugrana in the 2017/18 campaign. He contributed a lot to Barcelona's attacking play and at the same time solid at the back.
#4 Marc-Andre Ter Stegen 8.5 /10
Ter Stegen is one of the best goalkeepers in the world right now and deserves a lot of praise for his brilliance. He was spectacular between the sticks for Barcelona this season and made some stunning saves. Along with Pique, he is one other important factor behind Barcelona's stunning defensive stability under Valverde.
#3 Gerard Pique 8.5/10
Barcelona has the second best defensive record in all of Europe's top 5 leagues this season and Gerard Pique is at the heart of it. Barcelona only conceded 21 goals in La Liga this season. He made 42 appearances for Barcelona and was brilliant at the back throughout the campaign.
#2 Luis Suarez 9/10
After a subdued start to the 2017/18 season, Luis Suarez returned his best in November and from then on he was unstoppable. He has scored 29 goals and assisted 12 more in all competitions this season. He shared the goal scoring responsibilities with Messi and the duo complemented each other really well.
#1 Lionel Messi 9.5 /10
The Argentine is Barcelona's and La Liga's best player this season without the slightest of doubts. He is amongst the goals this season with 42 of them in all competitions for the Catalan giants. He also made 14 assists and created a total of 77 chances in La Liga. He will most likely win the Pichichi award this season.
