The 26-year-old has been pictured training with the Brazilian side today, although Man United are yet to officially confirm the move.
Speaking on Sky Sports News, Neville said: “He has had some really good performances, but not consistently and I wonder whether that has been because of fitness as he’s picked up a lot of injuries. He’ll look back at his Manchester United career with some level of disappointment.
He is a big-game player, has a big-game mentality, lots of skill but never was fit enough to be able to do it consistently, week in and out in the Premier League and that’s a real shame.
That’s when you have those players who look back at the end of their careers and wonder: ‘Could I have been that little bit more driven?’ He has the talent but lacked in other areas and was unfortunate with injuries.”
It had looked like Anderson might stay at Old Trafford after reports earlier in January suggested that there had been no interest from any club for the midfielder, but that situation has changed and now he looks set to finally move on.
Anderson has become something of a joke figure in recent years but he had initially enjoyed a good debut season at United. His United career peaked after scoring a penalty against Chelsea in United’s triumphant 2008 Champions League win but has deteriorated since then thanks to a succession of injuries, combined with a loss of motivation.
Despite his disappointing spell at United, he remains a popular figure in the dressing room and a number of United players have taken to social media to wish him well in Brazil.
Anderson may well be disappointed with how his Man United career has turned out but fans will have little sympathy for him given the eight years of frustration they have had to endure with him at the club.
