Michel Fabrizio says a lack of feeling on his Ducati Xerox was to blame for his failure to break into the top ten during the second round of the World Superbike Championship in Portugal.

A far cry from his race victory at the same circuit just four months ago, Fabrizio faced a tough task from 17th position on the grid, but he struggled to make speedy progress through the field, the Italian's cause being hampered by a handful of off-track moments.

Claiming he was unable to get the Ducati Xerox 1198 set-up to his liking, Fabrizio was disappointed with his mediocre 11th place finishes in both races.

"Let's say that this weekend we were not able to refine the set up of my 1198 as we had hoped to," he said. "I continued to have the same problem, the same lack of feeling at the front, in both races.

"We made many modifications over the weekend but it didn't make much difference; I just never felt right on the bike. At the start of race two I managed to make up a few places straight away by pushing as hard as I could but after a few laps it became more and more difficult to turn.

"I went off track a couple of times in race one and then I went straight two or three times in the next race. We of course hope for much better results at Valencia, where I need to start from the front rows."
