The Colombia international has hit 16 goals for current club Hertha Berlin this season but he will "develop" with Die Schwarzgelben, believes their 46-year-old coach
BVB announced in midweek that the Colombia international, who has hit 16 Bundesliga goals this season, will join them this summer.
Ramos has essentially been signed as a replacement for the Bayern Munich-bound Robert Lewandowski and Klopp is in no doubt that the 28-year-old will fit right in at Dortmund.
"Adrian Ramos is a very good player and he never scored more goals than in this season," he told reporters.
"He works very hard, is very calm in front of the goal and good in ball possession. We are sure he can develop at Borussia Dortmund. We are very pleased the transfer was successful."
Klopp is currently preparing his side for Saturday's Bundesliga clash with Bayern Munich at the Allianz Arena, with Dortmund hoping to upset the newly crowned champions in order to maintain their grip on second place.
Indeed, while BVB face Wolfsburg in the DFB-Pokal semi-finals on Tuesday, the 46-year-old intends to field his strongest possible starting line-up in Bavaria.
"I have to see who will be available for Saturday against Bayern Munich and I have not decided yet," Klopp said of his injury-ravaged squad.
"Next Tuesday [against Wolfsburg] is the end of four (tough) weeks but, in Munich, it is about three points.
"I don't know what [Bayern] plan on Wednesday [in their DFB-Pokal semi-final] against Kaiserslautern; probably they won't be challenged that much. We will not give something away, however, we also have to see who will be available."
