There are so many transfer rumours surrounding clubs and players that it's hard to remember that January is still more than a month away.
And clubs like United, who didn't make any serious impact in the summer transfer window, are desperate to catch hold of some quality players come January.
It seems that players like Sami Khedira, Marco Reus and Radamel Falcao are top targets for some clubs and they would love to take place of some senior players who are not what they once used to be.
But these players who are rumoured to join some giant clubs in January remind me of those players who should have never left their former clubs, like Andy Carroll.
They turned out to be a super-flops for their next club and never showed their actual potential.
Due to a plethora of reasons such as super stardom, appeal to the fans, or massive potential, the departures of these players left the fans disappointed and maybe even saddened.
So, here are the players who should have never left their clubs.
5. Robbie Keane (Tottenham to Liverpool)
This transfer was considered to be a big transfer, not in terms of money but in terms of the quality of the player.
Tottenham confirmed the sale of Keane for £19m in July 2008, but he never got going at Merseyside.
A limited number of appearances led to a disappointing five goals for the Irishman.
The "devastating" presence of Fernando Torres and Dutchman Dirk Kuyt made life difficult for Keane at Liverpool. Finally, just after a season he was pulled out of his misery by his former club Spurs, when they re-signed him for £12m.
4. Alex Hleb (Arsenal to Barcelona)
He's one of the better players who actually regretted leaving their former club Arsenal. In July 2008, a medical examination was held for the player at FC Barcelona, with his transfer completed later that day for a fee of €15m plus an additional €2m if Barcelona won the La Liga title in 2008–09 or 2009–10 (which they did in 2008–09, bringing his total fee to €17m).
Hleb signed a four-year contract, with a buy-out clause of €90m. His time at Barca was worse than what Keane had at Liverpool: no goals in 19 matches which, for an attacking midfielder and a winger, is not acceptable.
3. Shaun Wright-Philips (Man City to Chelsea)
If you make a move from a mid-table outfit (scoring 26 goals) to a top club and score just four goals in 89 games, then something's wrong with you.
Wright-Phillips completed a £21m move to Premier League champions Chelsea, returning to his native London.
He joined the club on a five-year contract after agreeing to personal terms and passing a medical. Having made 65 starting appearances for the club, with a further 60 as a substitute, Wright-Phillips had been unable to secure a regular place in the side under Grant and Mourinho.
His falling out with new boss Luiz Felipe Scolari meant that he was allowed to leave. Maybe the downfall of his skills and quality started then and there.
2. Alberto Aquilani (AS Roma to Liverpool)
The Italian was considered to be a perfect replacement for outgoing Liverpool playmaker Xabi Alonso. He was signed for €20m and was handed over the number four jersey, which was last worn by Sami Hyypia.
Unfortunately he suffered from injuries from the start of his stint at Liverpool and unable to find his feet at Anfield.
Was sent out on loan to Juventus and later Milan after moving permanently to Fiorentina. The flair he possessed in his passing abilities at Roma was great to see but not enough game time and injuries proved to be a huge factor in his transfer being labelled as a flop.
1. Per Kroldrup (Udinese to Everton)
People would say that Fernando Torres would have been more appropriate but since, he's still at Chelsea you just cant say anything right now.
Kroldrup moved from Udinese to English club Everton on a four-year deal for a transfer fee of £5m.
But he suffered a groin injury well before the start of the season and had to undergo a surgery.
"Luckily" he could play just a single game and that was also a 4-0 drubbing by Aston Villa and his has been described as the worst transfer ever in history.
And later, Krøldrup has stated his difficulties of adapting to the physical aspects of the English game. Finally,Krøldrup transferred back to Italy on in January 2006, when he joined ACF Fiorentina, 31 days after his Everton debut.
