Transfer fee: £27.23 million (transfermrkt.com)
After an immense World Cup campaign with Colombia, Yerry Mina came into a big spotlight. Reportedly, Manchester United and Arsenal were keen to acquire the signatures of highly rated Colombian but however, in the end, Merseyside outfit Everton shockingly completed a blockbuster deal rising to the extent of £27.23 million. Everton also makes a list 'winners' of the transfer window as the Premier League outfit ingressed the transfer window very dominantly under the new management of Portuguese tactician, Marko Silva.
Barcelona, who were initially adamant to drop their £35 million valuations of the international Colombian, settled on a fee of £27.23 million with Everton.
Despite a very high profile deadline day move to England, Mina is yet to make Everton squad following an injury he suffered. However, the latest report claims the Colombian defensive ace could make his first competitive debut for Everton on 16 September when they face West Ham at Goodison Park.
