1. Jackson Martinez
Jackson Martinez was the most clinical striker in European football last year, according the the Uefa stats.
The Porto striker has been in terrific form for Porto over the last 12 months and has inspired interest from a number of top clubs including Arsenal and Chelsea.
Having scored 30 goals and converting 35% of his shots, Martinez may well justify the £34m fee Porto are reportedly demanding.
However, until Martinez moves to one of the top five leagues in Europe, it's unlikely we'll see him in any world XIs.
