Rossi words not mine, and he didn't ... hector in the back from what I read.......
I guess from our armchairs and the few cut aways we got on the feed you could deduce categorically, when considering Hectors involved, Rossi imagined it and/or is lying........And he said it would have made little difference anyway.
There were a number of times on the footage where Rossi (and Hayden for that matter) were behind Barbera but at no point did they seem to be held up by him etc.
Actually the closest I saw to a holding up of Rossi was actually (sorry Jums) Hayden who slowed coming out of a right hand corner (seemingly happy with the run) and did seem to baulk Rossi inadvertently with around 3 minutes to go in the session. The baulk was not that pronounced but the speed differential did make Rossi go hard right (his right) to get around Hayden who had realised and tried to speed up out of the way.
Aside from that, I did not see Barbera even following and reading his comments, he did not feel the need to do so.
