James Toseland says he could have been more aggressive in his attempts to snatch a fourth place finish from Leon Haslam in the second World Superbike race at Silverstone, but admits he favoured caution in reference to his countryman's title hopes.

Toseland fought back from a disappointing qualifying performance that left him in 12th to put in a spirited showing during the races, not least in the second encounter when a switch to a set-up more akin to what his race winning team-mate Cal Crutchlow was using allowed him to make swift progress.

Getting embroiled in the fight for fourth, Toseland and Haslam battled it out over the final laps, the pair even briefly touching as they entered the finishing straight for the final time. However, the former champion says there was little use in getting aggressive if would hamper Haslam's title challenge.

"Race one was ok, the set up we used wasn't perfect but I made the most of it," Toseland, who would come away with a fifth and eighth, said. "We made a massive change from race one to race two, we switched to something closer to what Cal was using in the first race, it's the first time we tried it and it really helped us. Hopefully we've found a good direction for the next race.

"A big thanks to the team for the change between the races, it got me from where I was in the first to not too far off the podium in the second. Leon Haslam rode a great race and really covered his lines, I could have been more aggressive with him but I didn't want to spoil his championship chances."
