Throughout football's history, clubs have regularly employed loan moves to bolster their squads on a short-term basis.
Sometimes, clubs sign players to fill in for their injured regulars until they recover from serious injuries. Other times, loan moves are employed to aid the development of young players, with their parent clubs sending them to relatively smaller teams where they are much likelier to get more game time.
Also, some players move on loan in order to regain their confidence and form after a rough spell in their career.
However, these loan moves do not always turn out the way the clubs have planned them. So without further ado, here is a list of five high-profile loan moves that did not work out for either party involved.
#5 Andy Goram (Motherwell to Manchester United)
Retired Scottish goalkeeper Andy Goram is widely remembered as a goalkeeping great. He played for Oldham Athletic, Hibernian, Rangers, Sheffield United and Motherwell, among a number of big clubs in the United Kingdom.
Goram was voted as the Greatest goalkeeper in the history of Rangers in 2001 after he achieved great success in his career at the club.
His stellar career had only one small blemish, a loan spell at Manchester United.
Goram joined Manchester United in 2001 on an emergency loan deal for £100,000 after Fabien Barthez and Raimond van der Gouw picked up injuries. Then 36, the goalkeeper was on the verge of being released by Motherwell as his contract was coming to an end.
Goram managed to feature only twice for the Red Devils, against Coventry City and Southampton, and he was substituted off both times.
Goram's spell at Old Trafford did not diminish his legacy as he remains the only goalkeeper in history to win both the English and Scottish league titles. In 2010, he was voted into Scottish Football's Hall of Fame.
#4 Kim Kallstrom (Spartak Moscow to Arsenal)
Swedish midfielder Kim Kallstrom was an emergency signing for Arsenal in January 2014 on loan from Spartak Moscow. The now-retired Swede failed to make his mark at the Emirates after arriving at the club.
Kallstrom was a last-minute deadline day reinforcement who Arsenal agreed to sign despite a broken back the player suffered in a training session with his former club.
The midfielder spent most of his time at the club on the treatment table, making only four appearances for the Gunners. He, however, helped the club end their nine-year trophy drought with their FA Cup final triumph over Hull City. He even scored in the penalty shootout win over Wigan Athletic in the semifinals of the competition.
The midfielder retired from professional football in December 2017.
#3 Radamel Falcao (AS Monaco to Manchester United and Chelsea)
At FC Porto and then Atletico Madrid, Colombian striker Radamel Falcao was one of the most sought-after strikers in world football. The striker moved to AS Monaco where he settled in quickly before a serious knee injury caused problems for him. In a bid to play in the 2014 FIFA World Cup, Falcao was rushed back.
The striker secured a deadline day loan move to Manchester United, where he was to earn around £265,000 weekly. His deal included an option to sign permanently for £43.5 million, and the club paid £6 million for the loan deal.
Falcao made 29 appearances for the club and scored only four goals, leading to the Red Devils' refusal to sign him permanently.
After returning to Monaco, Chelsea decided to pay £4 million to sign Falcao on loan with a £38 million option to buy. The Colombian was paid £170,000 weekly, and made only 12 appearances for the club. He scored only one goal before his loan was terminated.
Falcao currently plays for Rayo Vallecano in La Liga. The 36-year-old striker remains one of the most important players for the side.
#2 Ricky Alvarez (Inter Milan to Sunderland)
Argentine winger Ricky Alvarez is remembered by the Sunderland faithful as one of the worst signings in their history. He joined the club from Inter Milan on loan in September 2014.
Alvarez joined Sunderland as the club looked to beat the drop from the Premier League. A clause to sign him permanently was included in the deal, with the condition being that Sunderland had to avoid relegation.
Alvarez suffered a knee injury during his loan spell that limited him to only 13 games for the club, but Sunderland avoided relegation and were forced to sign him permanently. The Black Cats entered into a legal battle with Inter and lost at the CAS. They ended up spending up to £20 million in compensation.
Alvarez never played for Sunderland again, as his contract at the club was not renewed after his loan deal. He later joined Sampdoria on a free transfer.
#1 Alexandre Pato (Corinthians to Chelsea)
Brazilian striker Alexandre Pato was a teenage sensation when he broke out as a rising star in Brazil. The striker enjoyed a brilliant goalscoring spell in Italy with AC Milan before injuries derailed his career.
Pato joined Chelsea in January 2016 on a loan deal from Brazilian giants Corinthians, but the Brazil international made only two appearances for the club.
He scored one goal for the London-based side from the penalty spot against Aston Villa. Chelsea refused to sign the striker permanently after his loan spell at the club came to an end, and he returned to Corinthians.
Pato saw a promising career go downhill due to a number of niggling injuries. Still only 32 years old, the striker currently plays for Orlando City FC in Major League Soccer.
