JONATHAN Rea finished fifth in the first race and sixth in the second at the World Superbike round at Donington yesterday (Sunday).
However the Castletown resident was not happy with his results.
The Northern Irishman, who rides for the Castrol Honda team, said: "We got through the weekend OK but fifth and sixth is not what we came here for and, by my own standards, 'OK' is not good enough.
"I've tried my best all weekend but I got duffed up a bit in race one and maybe could've finished a bit higher.
"In race two I didn't make any mistakes and rode as well as I could so it was frustrating when the other guys came past.
"They seemed to be able to ride away from me quite easily while I was on the maximum.
"We tried to use the softer tyre during the weekend but it tore up after 10 or 12 laps so I'm not sure if it would have made any difference.
"We've got some work to do, I think – especially on the electronics side of things to get driveability off slower corners.
"Luckily for us Assen hasn't got the stop-go slower section that we have here, so I’m looking forward to getting there for a bit of flow.
"At the end of the day we were sort of 'on par' here, but we need to be better than that, especially at this stage in the season.
"We don't want the guys at the front to be opening this much of a gap, so we need to be on it from the next round."
The first race was won by Italian Marco Melandri riding for Yamaha while the second was won by Spanish rider and championship leader Carlos Checa riding for Ducati.
