The world number two is making his return from an elbow injury and is looking for a boost after a poor start to the season.

Spain are without Rafa Nadal, who opted to miss a tie to be played on hardcourt in favour of focusing on his preparations for the start of the clay-court season.

Viktor Troicki and Pablo Carreno-Busta will clash in the other singles rubber on Friday.

The winners of this tie will go through to a semi-final against either France or Great Britain.
