Reports have again started to escalate that Robin van Persie is unhappy with life under new manager David Moyes, with his old club doing so well, should he regret leaving the Emirates?
The Dutch star joined Manchester United last summer from Premier League rivals Arsenal in a controversial £24m deal.
At the time he said that the chance of working under Sir Alex Ferguson was a main reason for the move to Old Trafford, although Van Persie was not to know that one of the greatest managers of all time was going to retire.
In that statement he put on his website before his departure from Arsenal, he said: "I personally have had a great season but my goal has been to win trophies with the team and to bring the club back to its glory days."
His wish came true last season, with United easily winning the Premier League title in Fergies' last season in charge. Van Persie scored 26 goals and won also a trophy of his own in the form of the Golden Boot.
But it hasn't happened this season, well we don't expect it to. The Manchester faithful could go 15 points behind the club he once left tomorrow.
According to the Daily Mirror, Van Persie is growing increasingly frustrated with the Scotsman and apparently handed in a transfer request, even though that report was today rejected by manager Moyes.
It is almost undeniable that the green jealousy bug has affected Van Persie, when looking at Arsenal's success this season compared to Manchester United's failure he is bound to wish he was back in London.
So perhaps it was a mistake to leave the Gunners? If he had stayed he could have propelled them higher than third last season, and this season would have been plying his trade along with the likes of Mesut Ozil this season.
The 30-year-old Dutchman does not have long left at all at the top level, his grey hair gets more and more noticeable each week and his injuries are slowly becoming more and more frequent.
Unfortunately for him, the retirement of Sir Alex Ferguson has left his left Manchester United in failure mode, and has now gone to the extent of Van Persie now considering his future.
United had the chance to hire a world-class manager, who had the ability to pull in the best players of Europe's elite, although were slow on the uptake and didn't take their chance.
All summer long Moyes tried to bring in a big name to win over the fans, although none came. Thiago Alcantara and reportedly Mesut Ozil turned down the chance to join the club in favour of working with more highly regarded managers such as Pep Guardiola and Jose Mourinho, people who the powers that be should of considered hiring as the new gaffer.
As United stood still, or even moved backwards their rivals all improved somewhat, Manchester United will not win a trophy this season - something which Van Persie moved to the club to get.
Van Persie will watch as Arsenal go from strength to strength over the next few years, with one of the most experienced managers in the world at the helm and cash flooding in from corporate sponsorship deals nothing could go wrong for the Gunners.
The Gunners will surely challenge for this year's title, as well as the other major trophies, something what Van Persie left the club to get. Ozil, along with the help of Olivier Giroud and Aaron Ramsey will surely elevate them to the top of the Premier League once again.
Meanwhile, the future looks grim for United. I can guarantee that it will be a few years and trophies yet before Moyes has a good enough pulling power. By the time Moyes can attract someone like Ozil or such like, Van Persie will be sat twiddling his thumbs in his mansion, retired.
But even then it won't mean Moyes will get the players, with Chelsea's Jose Mourinho also to contend with as he to battles it out for the same trophies as well as the same players in the transfer market.
United are all set for a very dry spell in the transfer department, and their trophy cabinet will lay bare for a few more years yet.
No one doubts that Moyes has the right to be a great manager, but his lack of experience and reputation at this stage will only get in the way of his chances in Manchester.
If Van Persie wants to win trophies - which I have no doubt that he does, he would be better to take another high profile move elsewhere, even back to Arsenal if it came too it.
The Dutchman will have to quickly change his 'grass is greener on the other side' attitude if he wants to succeed in football.
