da fazobetai： It's set to be a busy summer of incomings and outgoings at Stamford Bridge, but who is the club most likely to spend big on?

da bet nacional： After two transfer windows of unprecedented expenditure, Chelsea are facing what will be a defining summer in the club's modern history. Incoming head coach Mauricio Pochettino will be charged first and foremost with trimming the blubber from a bloated squad packed full of underperforming talent, but there is some targeted spending to be done, too.

Pochettino is believed to want a new core of players; a goalkeeper, central midfielder and striker are top of his shopping list, while Premier League experience is a bonus. One deal is already tied up, but who else are Chelsea most likely to sign in the upcoming transfer window?

GOAL runs through the names below…

A shoo-in. While we are still awaiting an announcement, by all accounts Chelsea are certain to bring in RB Leipzig forward Christopher Nkunku as soon as the window opens in mid-June. A deal has been in place for some time, with the Blues set to fork out £52 million ($64m) on the Frenchman.

It's a move that will raise some eyebrows given the Blues' already overflowing attacking ranks, but you need only take a quick glance at the 25-year-old's output to understand that he be a significant upgrade on the current batch of ineffectual forward players – with an injury-hit 20-goal season following a ridiculous campaign where he made 55 goal contributions.

However, Chelsea have been stung in the past with big-money signings from Leipzig…

A host of leading clubs are certain to be queuing up for Romeo Lavia after Southampton dropped out of the Premier League. There's no way in hell he's going down with them. It's been widely reported that Chelsea will pursue a new No.6, with incoming manager Pochettino seeking Premier League experience to form the new core of his side, and NXGN Nine inductee Lavia may well fit the bill.

His press-resistance, ball-carrying ability and progressive passing would unquestionably be an asset to Chelsea, in an area of the pitch where they are lacking a player with the quality to supplement January arrival Enzo Fernandez. He is now certain to be available for a cut price after the Saints suffered relegation; Lord knows Chelsea could do with saving themselves some cash this summer.

The jury will be out on whether Chelsea should pursue another deal for Joao Felix after his short-term loan at Stamford Bridge. A permanent transfer should be out of the question, with Atletico Madrid still demanding €100m (£87m/$107m) for the mercurial attacker.

However, a second temporary deal would make sense if an agreement can be found for a relatively low fee. Although his form has oscillated, Felix has largely been one of Chelsea best performers in an extremely challenging period for the club, scoring four of the club's measly 15 goals since he signed in January. It would be fascinating to see the possibilities in an in-form side – at his flying best he has shown that he can be truly world-class.

What's more, he seems genuinely happy at Stamford Bridge, although Chelsea's failure to qualify for the Champions League could be a factor in his decision-making. "I don't know yet about my future," he said recently. "It's four or five months and I love it. It's a top club, everyone in the club was very good to me. My team-mates were unbelievable and I really like to be here."

Chelsea will pursue a new goalkeeper this summer, and Inter's Andre Onana currently seems like the most likely option. There will be very few objections to the decision among the fanbase, with neither Kepa Arrizabalaga nor Edouard Mendy proving themselves to be long-term No.1 options for an elite football club, although the former enjoyed an improved season between the sticks.

Onana fits the archetype of the desirable modern-day goalkeeper, equally as comfortable stepping out from the back to become a pseudo extra centre-back as he is commanding his penalty area. His agility and shot-stopping ability are exceptional, and given Inter's well-documented financial struggles, he would potentially be a cheaper option.
