When Uruguayan superstar Luis Suarez arrived at Barcelona from Liverpool in 2014, the deal was met by a few raised eyebrows.
Of course, no one doubted the striker's ability, but his controversial reputation and impending suspension led many to question his vastly expensive arrival.
However, such doubts have since been well and truly put to bed, with 2015/16 representing the year Suarez confirmed himself as possibly the finest out-and-out striker in world football.

Robert Lewandowski, Sergio Aguero and Zlatan Ibrahimovic can all lay claim to the prestigious title, but Barcelona's number nine is just that extra bit better.
What Suarez has achieved during his short stay is nothing short of remarkable - his eye for goal, movement and overall contributions have made Barcelona's front-line better than anyone could have imagined.

His arrival within Luis Enrique's setup saw Lionel Messi shifted back out to the right-hand side, the position in which he began his career and a move which has paid dividends.
Suarez has taken up the central role vacated by Barcelona's mercurial talisman and provided a service which few in world football can match.
Not only has he scored a high volume of goals - 36 in 34 games so far this season - but he has given Barcelona a different dimension; a different output for which they can break down stubborn opposition.
Barcelona had previously been accused of sticking to their same methods of tiki-taka to break down teams, rarely varying their approach and suffering against sides who chose to overpower them.
Upon Suarez's introduction, though, with his strength, positional sense and movement, Enrique's men were able to effectively utilise the long ball.
For example, the 29-year-old's winning strike against Real Madrid at the Camp Nou last season came from a Dani Alves' searching pass from deep, while another goal during a vital 2-1 win over Atletico Madrid recently came from a ball over the top.
NO LONGER RELIANT ON MESSI
When Barcelona's Argentine superstar was ruled out for two months earlier this season it was thought the Blaugrana would suffer. In recent years, they have struggled to perform to an acceptable standard without their main man - but this time was different.
Having Neymar undoubtedly eased the impact Messi's absence held, but Suarez took on the challenge and helped maintain Barcelona's high standards with his goals and sensational link-up and hold-up play.
He and his Brazilian teammate scored 18 La Liga goals between them in late 2015, further demonstarting their offensive capabilities.
In recent weeks, with Messi back to full fitness, Suarez has continued his impressive form and arguably thrived more from the Argentina international's playmaking qualities.
His runs in behind give Messi options with which to demonstrate his passing range, while Suarez's unselfish style of play provides more space for his partners in crime to exploit.
Barcelona have boasted their fare share of incredible attacking trios over the past decade, but none compare to the current threesome of MSN (Messi-Suarez-Neymar), who have scored 48 of their side's 56 La Liga goals this season with 16 still to play.
