Every now and then, the world's top teams release or sell players who end up making them regret their decision.
In the past few years, certain regrettable transfers have become more noticeable then others. Here are five of the most evident.
5: Gerard Pique: Manchester United to Barcelona
Gerard Pique made his debut for Manchester United as a striker in October 2004. His most notable performances were for United's reserve team, but he was still a solid first team replacement for when Gary Neville was injured. His reserve team performances earned him a new contract in 2005 which was supposed to last until the summer of 2009.
After a brief spell at Real Zaragoza on loan in the 2006/07 campaign, Pique returned to Old Trafford but not for too long. In May of 2008, Pique signed with Barcelona for an extremely low £4 million fee. Ever since then, Pique has been a key asset in Barcelona's glory. What a deal for Barca. Sir Alex Ferguson does not usually make mistakes, but that's one transfer that didn't go as he planned.
4: Samir Nasri: Arsenal to Manchester City
In the past few seasons, legendary Arsenal manager, Arsene Wenger has been criticised for his decisions in the transfer windows. One of the most memorable decisions lead to the departure of french magician, Samir Nasri. Samir Nasri was a star figure in the Arsenal squad, playing along side Song and Van Persie for several seasons, creating and scoring some astonishing goals. Unfortunately for Arsenal, the midfielder left for Manchester City in 2011.
Nasri won the Premier League that year, while Arsenal ended up in third, nineteen points behind the League winners. Nasri was always a class act when playing for Arsenal. I'm sure he is missed greatly at the Emirates.
3: Cesc Fabregas: Arsenal to Barcelona
During his time in the Premier League, Cesc Fabregas was known as one of the most intelligent and committed footballers around. His unique vision and inspiring attitude made him one of the most valuable players in England.
As many do, Fabregas transferred from the Premier League to La Liga. Since leaving Arsenal, Fabregas has had a solid few seasons with Barcelona, but is sadly not as appreciated as he was at Arsenal. A true legend for the Gunners, that will be remembered for a long time. Another shock transfer from Wenger.
2: Daniel Sturridge: Chelsea to Liverpool
Chelsea are known for going on wild and very expensive shopping sprees during the transfer windows. However, this time they sold a potential star to a main rival which might not have been a great idea. Daniel Sturridge is an extremely skilful and threatening young player.
Age 23, Sturridge has his whole career ahead of him, and after playing for Manchester City, Bolton and Chelsea, Liverpool looks like the perfect fit for him. Since arriving in Merseyside, Sturridge has created quite a spectacular partnership with Luiz Suarez. The two have made and scored a large portion of Liverpool's goals this season, including the two goals in the 2-2 draw again Sturridge's former club, Chelsea. Even though Chelsea have a notoriously fierce arsenal of young players just waiting for their time to shine, Sturridge could be one they truly regret selling.
1: Robin van Persie: Arsenal to Manchester United
Possibly the world's best striker. A deadly force in front of goal. A phenomenally powerful and accurate left foot. Robin Van Persie has really shown his full potential this season.
After signing for Manchester United in August 2012, RVP has been one of the most influential and effective player's in the Red Devil's squad. He is the Premier League's top scorer this season with over twenty goals.
Three of which came in fantastic performance that officially crowned United as champions. Robin Van Persie's form has given him a reputation as one of the most lethal strikers in the world. Once again, Wenger's transfer tactics haven't worked out too well. Robin van Persie adores Arsenal but there's no doubt he is enjoying his time at Old Trafford.
