#5 Pontus Jansson (Leeds United)
Pontus Jansson was bought by Leeds United for a cool £3m back in July 2017. His former club Torino must have overlooked the centre-back's ability, because he's now worth almost double that price, and it's only been a year.
Jansson featured in 42 of the 46 matches for Leeds in the Championship last year, where he solidified his place in the starting eleven thanks to a long string of superb performances. He was also selected to play for his country, Sweden, in the World Cup this summer. He made two appearances for the Swedes before they were knocked out in the quarterfinals by England.
Where might Pontus Jansson end up?
The Sun reported that Southampton were prepared to line up a bid for Jansson this summer, but nothing has materialised as of yet. There has been speculation surrounding a move to the Premier League for some time now, but until an official move is made, he will stay put.
