Aprilia MotoGP rider Scott Redding admits he 'lost his mind' during last weekend's French Grand Prix amid the pressure to show he deserves to retain his seat.
Redding has scored only five points in as many races so far in 2018, having said in Jerez earlier this month he felt time was "running out" to prove himself worthy of a new contract at Aprilia.
Despite taking part in two days of testing at Mugello a week prior to the French GP, the Briton couldn't improve at Le Mans either as he qualified 22nd and crashed out in the race.
Speaking post-race, Redding admitted he was struggling to deal with the ever-increasing pressure, but said he "cannot show anything" with the current Aprilia RS-GP.
When asked if the French GP was a bad weekend for his future, he said: "I don't know, but f***, I can't do anything about it.
"I f***ing lost my mind yesterday [Saturday], I come in and I have pressure to show results but I cannot show anything. When I try to show [something], I crash.
"It is not easy because it is always in your mind, and you think 'okay, now this weekend will be better, you're in the safe zone.' I'm even more in the shit than I was before the weekend.
"The f***ing thing doesn't work for me at the moment, and like I said yesterday, we tried [everything], the bike is inside out from Jerez, completely opposite.
"Mugello [testing] feels good, come here, it's a f***ing waste of time. Makes no sense to go testing because it seems we always come back anyway."
Redding added he would be "pissed off" if Aprilia announced an alternative rider for 2019 and then subsequently found a fix that would allow him to achieve good results.
However, the Briton said that if Aprilia doesn't improve his bike for the remainder of 2018, he wouldn't want to stay with the team anyway.
"If it is like this, I cannot show myself," he said. "What do you want me to do? I cannot work miracles.
"The thing that would annoy me is if they replace me with another rider, then they bring some new parts, and I can show my potential. Then I'll be pissed off.
"If it is like this until the end of the year and I cannot figure out the problem, hey, I anyway wouldn't want to stay on again for another year if I'm struggling like [this]."
Among the candidates to replace Redding are Andrea Iannone, who looks certain to lose his current ride at Suzuki, and Danilo Petrucci, who is targeting a move up to Ducati's works team but also has an offer from the Noale marque on the table.
