Robbie Williams is said to be confident of his category winning The X Factor 2018.
Robbie is one of three new X Factor judges alongside Ayda Williams and One Direction star Louis Tomlinson.
They sit alongside Simon Cowell on the panel, with Sharon Osbourne joining them for the live shows later in the year.
During the week, the judges filmed the six chair challenge after the X Factor judges' categories were revealed.
Take That star Robbie has the groups and is reportedly confident of his chances.
According to The Sun, at the six chair challenge a number of new acts were introduced including a duo put together by wife Ayda.
A source spilled: "It’s still really early in the process, especially as viewers haven’t had their say yet.
“But Robbie is convinced he’s got it in the bag and his wife Ayda Field, Simon Cowell and Louis Tomlinson have all had to admit he has a strong category.”
Speaking backstage at Wembley during filming, Robbie said: "So we've just done six chairs for the first time and everyone thing previous to that has been a walk in the park.
"I honestly didn't know what we were letting ourselves in for. The motions you feel the vibe from the audience, the ups and downs are incredible.
"I'm really not looking forward to doing mine because there were some tough choices sending people back to where they come from or they stay on their journey to follow their dream."
Those through the six chair challenge will fly off with Robbie for judges' houses.
At judges' houses, acts will compete to make the live shows.
The X Factor 2018 will start on ITV later this year.
