Feliciano Lopez and Fernando Verdasco are well aware their partnership in the Davis Cup is far from excellent. After a very poor performance in the semifinal against France (6-1, 6-2, 6-0) in September, the Spanish duo had chosen to play doubles together in Shanghai, Valencia and Bercy in order to get ready for the final in December against Argentina.

But in Shanghai, the Spaniards lost in the first round to Thomaz Belluci and Ivan Dodig. They also lost in Valencia last week against Daniel Gimeno-Traver and Pere Riba. What about tomorrow at Bercy against Colin Fleming and Jamie Murray?

Behind the scenes, the question is clear: Is this pair really the one to call for the final? And are they able to make it?

It is probably difficult to try to answer this question that Albert Costa, the captain of the Spanish team, posed when he came to Paris this week. Tomorrow he will attend Lopez's and Verdasco's double against Colin Fleming and Jamie Murray.

In case of further collapse in Paris, the Spaniards could be seriously worried, as Marcel Granollers' and Marc Lopez's current great performances could oust the duo originally planned.
