Cardle took to Twitter today (December 9) to send support to Arthur but addressed the comments he was reported to have made to The Mirror.
James Arthur reportedly said that the previous male X Factor winners have not been successful as they have released poor material.
He said: "I find the statistics ridiculous, the blokes that have won before have had a niche, they haven't sold records because they haven't made great albums. That's the bottom line.
"This show has evolved. If either me or Jahmene won, the albums will be good and they will sell.
"There's creative control this year, there hasn't been that before."
He went on to say that previous winners have had to "compromise".
Cardle responded: "@JamesArthur23 I think you are so talented bro and I really hope you win tonight, but you haven't sold 2 million records... yet...
"@JamesArthur23 … you haven't had two Top 10 albums… yet. So disappointed you're slagging off my work and my career.
"@JamesArthur23 you're not just slagging me off, but Eg White, Biff Stannard, Steve Booker, and so many other incredible writer producers."
He ended by tweeting: "I appreciate everyone's opinion. I've ALWAYS said James is an amazing talent but today he has slagged off my work in the press. Disappointing."
