Defending Bundesliga champions Borussia Dortmund have joined Manchester United and Liverpool in the race to sign Porto forward Jackson Martinez, according to talkSPORT.

The Colombian international has been in sensational form for his Portuguese club, bagging 23 goals in 23 league appearances while adding another three in the Champions League. His superb goalscoring form has alerted Europe’s top clubs with Barcelona and Juventus joining United, Liverpool and Dortmund in the chase for his signature.

Reports in Germany this week claim that Jurgen Klopp’s side see the forward as the ideal spearhead for their talented attack.

With doubts surrounding the future of Robert Lewandowski, the German giants are considering their summer options, with Martinez thought to be a potential replacement.

Dortmund already boast one of the most exciting, young forward lines in Europe. Marco Reus, Mario Gotze and Lewandowski have been superb in this year’s Champions League competition, and the addition of Martinez would strengthen them further.

The report claims United and Liverpool now face a battle to land the Colombian, as Dortmund have asked for talks with Porto representatives regarding a summer transfer.

The 26-year-old Martinez was signed by Porto as a replacement for the departed Radamel Falcao. Martinez replaced his international teammate in the Porto starting lineup after joining the club in July 2012, and he’s hit the ground running in Portugal.

Liverpool and United have both been linked with a move for the forward, who signed for Porto from Mexican side Jaguares. But with Barcelona, Dortmund and Juventus waiting in the wings, it could be a European wide scrap for his signature at the end of the season.
