‘He needs to win on Saturday. I don’t know where he would go from there if he doesn’t,’ Pickett told Metro.co.uk.
‘Results matter. I think Conor’s mistake in the past has been looking at the bigger picture, rather than the fight in front of him.
‘He has his fingers in so many pies and he can lose focus on what is actually in front of him.
‘That’s Donald Cerrone. He can’t be thinking about boxing or Manny Pacquiao or a Floyd Mayweather rematch.
‘He needs to beat Cerrone this Saturday before he talks about anything else.’
McGregor has insisted during the build-up that he has re-committed himself to MMA after allowing his fame to distract him from fighting.
The former lightweight and featherweight UFC champion has branded 2020 his ‘season’ and intends to fight three times in the next 12 months.
Pickett said he was not surprised to hear McGregor’s latest comments, but still believes money remains the Notorious’ main motivation.
‘Conor would be saying he’s re-focused anyway, that’s what we all say,’ Pickett insisted.
‘As a fighter you have to be motivated to train. Competition always motivated me and when I started falling down rankings, I retired.
‘I didn’t know where I was going, there was no goal anymore and it felt like I was just fighting. Training suffered and eventually your focus goes.
‘Conor is very focused on making money and that seems to drive him at the moment.
‘He wants to be the highest paid athlete and on the Forbes list. He says he believes he’s going to make $80million [£61m] in his fight.
‘He’s earning more for Cerrone than he did for Khabib.
‘But he’s got to find something that motivates him. He needs to win on Saturday.
‘I don’t know where he would go from there if he doesn’t.’
‘People would still watch him, but his stock would fall further again.
‘He’d still be a massive draw, but his earning potential takes a massive hit if he loses.’
