The striker, who has been in excellent scoring form in 2013-14, will join Signal Iduna Park for an undisclosed fee at the end of the season

Borussia Dortmund have confirmed the summer signing of striker Adrian Ramos for an undisclosed fee to fill the void being left by Bayern Munich-bound Robert Lewandowski.

The Schwarzgelben were dumped out of the Champions League on Tuesday by Real Madrid at the quarter-final stage despite winning 2-0 in the second leg, but confirmation of Ramos' long-rumoured arrival on a four-year deal should help ease the pain of European elimination.

Ramos, 28, has been in super form this season, scoring 16 goals in 29 appearances, while his overall record with Hertha Berlin stands at 32 goals in 89 showings.

His form has led to a recall to Colombia's squad with Radamel Falcao's chances of being fit to feature at the World Cup this summer still up in the air and he is set to join up with the Schwarzgelben after the tournament.

BVB sporting director Michael Zorc, who had revealed this week that the club will "certainly sign two strikers" in the summer, lavished praise on the future Dortmund attacker and believes he is suited to Jurgen Klopp's squad.

"Adrian Ramos is an excellent footballer and one of the top goalscorers in Germany," he told the club's official website. "He fits perfectly with Borussia Dortmund's requirements."

Dortmund's statement confirming the deal also stated that the two clubs had agreed not to disclose the transfer fee.
