Manchester City may not know when their next transfer window will begin amid the shutdown caused by coronavirus but they have had some big hits in recent years.
Pep Guardiola has credited the scouting team for 80 per cent of the club's success and sporting director Txiki Begiristain has overseen a few surprises.
Big money buys such as Aymeric Laporte and Rodri have obviously made a big difference in improving the first team but there have also been players who have had a far bigger impact than was expected when they were signed - the ones not seen as marquee when they signed but whose value has gone up and up, the other end of the spectrum to the Wilfried Bonys and Eliaquim Mangala in City's balance books.
Here's a look at some of those successes.
Aleks Zinchenko, £1.7m, 2016
Zinchenko arrived in Guardiola's first transfer window in 2016 on the back of some promising displays for Ukraine in Euro 2016.
Then 19, he was promptly shipped off for a mediocre loan at Dutch side PSV, who showed little interest in helping to produce a player that wasn't theirs.
City welcomed Napoli interest the following summer, and even after Zinchenko had stayed and worked his way into the team the club were still happy to accept £16m from Wolves for him in 2018.
He rejected it, made the left-back spot his own with Benjamin Mendy continuing to struggle with injuries, and was rewarded with a five-year contract last June.
One of City's biggest bargain buys.
Frank Lampard, free, 2014
Lampard was never expected to do much more than train with the Blues as he waited to start a new life in the US as a Designated Player for City-owned New York City FC. The Chelsea legend had said he didn't want to play for another Premier League team, so Jose Mourinho wasn't too pleased to see the Stamford Bridge great come on and score an equaliser against the West London club for his new outfit.
So integral to Manuel Pellegrini's plans did Lampard become so quickly that City gave him another short-term contract beyond January, in the process delaying his start in MLS and angering the NYCFC fans that had been sold on how separate this new club was from the mothership in Manchester.
Kevin De Bruyne, £54m, 2015
It's arguable whether a record signing can have a bigger impact than expected but this was still a gamechanger for City as a club.
In 2015 they were still seen as having more money than sense; the Wolfsburg star was welcomed as a £60m flop on one unfortunate back page, while Liverpool were still smug at this point about getting £44m for Raheem Sterling.
Excellent in his first season at the club, De Bruyne has taken his game to another level and another planet under Guardiola and will surely pick up his third Player of the Year award in five attempts - having spent most of last year injured - when this season is eventually finished.
De Bruyne is now the best example of City spending money in the right way, with anyone who scoffed at the fee at the time now kicking themselves they weren't as sharp as the Blues when it mattered.
Aaron Mooy, free, 2016
Mooy never kicked a ball for Guardiola's first team but remains the shining example for anyone looking to use the City Football Group network.
Signed in 2016, he swiftly went on loan to unfashionable Championship side Huddersfield Town where he shone as they surprised many by earning promotion under David Wagner.
So good was the partnership that it was made permanent, with the Terriers paying £10m to have him with them in the Premier League. And so good is Mooy that Brighton swooped for him when Huddersfield's two-year stint in the division came to an end.
There have been many misses on players brought to Manchester in similar fashion, but Mooy is the bar for any aspiring newcomer to aim for.
Fabian Delph, £8m, 2015
Signed in the same window as De Bruyne and Sterling, Delph has not had the same impact as them but still became more important than he first looked.
City had seen a number of moves for the best players in teams lower down the division, with Scott Sinclair from Swansea and Jack Rodwell from Everton failing to impress.
Aston Villa's captain never really looked like doing more than offering squad depth to give Yaya Toure, James Milner and Fernandinho a rest but saw his career transformed by injury to Mendy in 2017.
He was an important part of the record-breaking City squad that won back-to-back titles in the last two seasons and, as the Amazon documentary and this season have shown, an invaluable member of the dressing room.
