Di Grassi not ruling out Pirelli test role

Luca di Grassi has dismissed reports linking him with a test driver role at Pirelli this year as "speculation".

But the Brazilian, who lost his Virgin race seat after just a single season in F1, admitted he might be interested in the tyre testing role.

Reports said di Grassi, 26, could be set to replace Pirelli’s secondary tester Romain Grosjean, who is returning to GP2 full-time in 2011.

"The news about Pirelli test driver role are just speculation at this stage but sure it would be interesting to understand the tyre better," di Grassi wrote on Twitter on Wednesday.
