'David Moyes never has any money to spend' - That's how the argument goes, but it's not strictly true.
Yes Everton's net spend may be among the lowest in the Premier League across the last five seasons, but they have still spent cash, it's just he has had to sell players too to balance the books.
Now manager of Manchester United, he will have no such financial worries, and can try to sign all the players he always wanted to but couldn't because of budget restraints.
His most expensive signing at £15 million was Marouane Fellaini who has been an unquantified success - as was £6 million Leighton Baines, but as Sir Alex Ferguson will testify; for every Eric Cantona there is an Eric Djemba-Djemba.
Here is a look at Moyes' five biggest transfer market flops:
James Beattie - £6 million
Everton splashed out on James Beattie back in January 2005, swayed by his terrific form for Southampton, becoming their club record signing at the time, but only scored one goal in the campaign he arrived. He failed to settle scoring just 13 league goals for the club, and is best remembered for a headbutt on Chelsea's William Gallas. He was sold in 2007 and now 35-years-old plays for Accrington Stanley.
Diniyar Bilyaletdinov - £9 million
Russian winger Bilyaletdinov stuck around just about long enough for fans to get the hang of pronouncing his name, but suffered from inconsistency at Everton. His highlight was a cracker scored in a 3-1 win over Manchester United, which won the club's goal of the season. He was the club's record signing when he arrived in 2009 but failed to build on a solid debut season. He ended up marginalised on the bench and even playing in the reserves before being sold to Spartak Moscow in 2012.
Andy Johnson - £8.5 million
Andy Johnson played one season in the Premier League with Crystal Palace in 2004-05 in which he was one of the most talked about players of the campaign. When they were relegated, Everton took a gamble on the striker's goalscoring talent a year later, again at the time a record signing. He scored 17 for Crystal Palace in one season, which was the amount he took two goals to score at Everton, and was again plagued by complaints over diving. The one plus was the club managed to sell him for a profit to Fulham.
Andy van der Meyde - £2 million
Dutch international Andy van der Meyde could have been an incredible signing for Everton, had he stayed fit and fulfilled his potential, but neither happened. The winger was a bargain signing from Inter Milan, but had off-field problems at the club and fell out with David Moyes over his fitness. In 2009 he was released after four seasons, and despite an attempt to rebuild his career in Holland, retired a year later.
Per Kroldrup - £5 million
Danish defender Per Kroldrup was signed by David Moyes back in 2005 from Udinese but failed to justify his price tag. After fitness problems, he was described as a 'rabbit in the headlights' when he was on the pitch, and later admitted he simply could not adapt to the pace and physicality of English football. He was sold to Fiorentina a year later where he spent six seasons, and now 33 plays for Italian side Pescara.
Which was the worst? Will Moyes buy well for United?
