#1 Luis Suarez
The best out and out striker this season, Luis Suarez has been exceptional for Barcelona and has at time almost single-handedly taken on the opposition defence. Alongside Neymar and Lionel Messi, Suarez has been deadly assisting and scoring at will ensuring his team cruise through.
He was always a talented striker be it in in Ajax days or his Liverpool days and has constantly proven at Barcelona that he and his team could do the impossible and actually defend the UEFA Champions League trophy. That achievement in itself reflects on the kind of form he's been on this season.
In his last four games, he's scored 2 goals and contributed 2 assists but against Real Madrid – a team who often deal with out and out strikers well – he has the potential to play a slightly deeper role and dictating the game from there. Either way, he'll be a huge asset for the Catalans this weekend and could potentially – as mentioned a billion times before – finish out of the title race in favour of his team.
