And Barton is quoted as saying by the Star: "West Ham's loss will be Burnley's gain.That's my honest belief.
"They've got their reasons for not doing it. I was happy to do it. But you lose one opportunity and another presents itself and I'm delighted to be here at Burnley.
"I think if you're a Premier League club - anyone from 10th downwards - and you had the opportunity to take me on a free transfer I think it's an absolute no-brainer."
Barton clearly hasn't lost any of his old confidence, especially in that he is aiming a dig at West Ham's Premier League position last campaign. And that may well be crucial at this late stage in his career when it comes to continuing to perform and helping Burnley in the Championship.
As always, though, it is no doubt a matter of over-confidence from the 32-year-old. Queens Park Rangers were a bottom-half club and he simply didn't have enough of an impact playing for the R's. Not only that but Barton found himself booked more often than not and sent off at crucial stages for QPR.
No, perhaps a top-half team could afford taking the risk of having Barton as a squad player. But a team finishing 10th or below - such as West Ham - couldn't afford the liability...
