Chelsea are set to take their spending under Todd Boehly to a whopping £1billion if they can get deals for Romeo Lavia and Michael Olise over the line. The American has splashed the cash since taking over at Stamford Bridge, backing Thomas Tuchel, Graham Potter and Mauricio Pochettino heavily in the transfer market. Here, the PA news agency takes a look at the biggest deals. Moses Caicedo (£115million) The Blues beat off competition from Liverpool for the signature of the highly-rated Brighton midfielder, who is the third most expensive under-21 player in the world behind Kylian Mbappe and Joao Felix. They paid £100m up front, but that could rise to £115m depending on certain criteria. Enzo Fernandez (£106.8m) Chelsea smashed the British transfer record when they signed the World Cup winner from Benfica in the January transfer window for an outright £106m, surpassing Jack Grealish’s fee for his move from Aston Villa to Manchester City. Mykhailo Mudryk (£88.5m) The Ukraine star cost £62million up front when he joined from Shakhtar Donetsk in January, but that fee could rise to £88.5m with possible add-ons. Wesley Fofana (£75m) Chelsea were after defensive reinforcements when they signed Wesley Fofana from Leicester. The France international cost £70million, with a possible further £5m to be paid to the Foxes in add-ons. Marc Cucurella (£63m) Chelsea have looked to Brighton on a number of occasions and, a few months before Graham Potter made the move from the Amex, the Blues signed left-back Cucurella for £56m, with a further £7m due in extras.
