It was originally believed that Williams would join his bandmates for one final LP and tour, but Gary Barlow has revealed that Williams has continued to work with the group on their new album.
"We really want that and this is our dream come true. At the beginning we all said it was going to last for one album, but we're starting to write again, so we don't know now," Barlow explained in an interview in the States, reports The Sun.
Claims that Williams is poised to sign a new solo deal led to speculation that he was to leave the band following their upcoming summer tour.
"Robbie is still desperate to be a solo artist and we can very much exist as a four," Barlow added.
Mark Owen has insisted that there have been no feuds that would lead to Williams's exit, which was the main cause for his departure from the band back in 1995.
"We are a team - at the moment Take That is five people, but it feels more than that. There's a lot of people who have a relationship with us," Owen stated.
"At the beginning there was a fragility to the whole thing, but that has gone now."
Barlow is allegedly days from signing a deal to join The X Factor, following Williams's rejection of a deal with the ITV1 talent show.
