Chelsea are ready to re-sign Romelu Lukaku this summer as Thomas Tuchel plots a Premier League title challenge.
The Blues want a new centre forward ahead of next season — with the Inter Milan hitman viewed as the most realistic target by club recruitment staff.
The newly-crowned European champions have built a formidable defensive record under Tuchel but have scored more than two goals in a game just once in 30 matches under the German.
Improvement in front of goal will be key if Tuchel is going to go challenge Manchester City for domestic supremacy next season.
Despite scoring 33 goals in helping Inter win Serie A last season, the Italian club will listen to offers for Lukaku as they seek to ease financial concerns.
Tuchel has already admitted he would be interested in signing Harry Kane from Tottenham but a deal for the England captain to join Chelsea appears virtually impossible due to the intense rivalry between the London clubs.
Borussia Dortmund striker Erling Haaland is also of interest to the Blues but a move for Lukaku is understood to be the club's main focus, with his advisors believed to be aware of Chelsea's interest.
Having signed for Chelsea as an 18-year-old in 2011, Lukaku made just one Premier League start for the club before successful loan spells at West Bromwich Albion and Everton, who he joined for £28 million in 2014.
Lukaku is now viewed as one of Europe's premier centre forwards and, at 28, is entering his prime. Inter are understood to value Lukaku at £100m but Chelsea will be keen to negotiate a lower price given Inter's need to sell.
Chelsea are also targeting a central midfielder and defender ahead of next season, with West Ham's Declan Rice a long-term midfield target.
On the prospect of adding to his squad, Tuchel said: 'Two or three could be very, very good. It's a constant thing to never deny change.
'Then you always bring new energy, new guys who question the old beliefs, who challenge everybody in the training and in matches. I think it's a good thing.
'We don't need a complete turnover because it's also our job to keep on improving. We have still a young squad that is capable of growing and evolving. But we have some ideas, of course, to make the group stronger.'
There are also set to be a number of outgoings with Callum Hudson-Odoi among the players whose future is uncertain as Borussia Dortmund plot to sign the England international.
The Blues academy graduate, who was previously a target for Bayern Munich, has fallen out of favour following a promising start to life under Tuchel.
It remains to be seen whether Chelsea are willing to entertain letting the 20-year-old leave this summer.
However, Sportsmail has learned they would be open to discussing a deal that included Dortmund's Jadon Sancho — who is a target for Manchester United — moving to Stamford Bridge.
Tammy Abraham, who was left out of the squad for the Champions League final win over City, is also resigned to leaving the club this summer. Fellow striker Olivier Giroud is expected to follow him out the door when his contract expires next month.
Central defender Fikayo Tomori is set to join AC Milan on a permanent deal following a successful loan spell in Italy, while midfielder Billy Gilmour will be a loan target for a number of Premier League teams.
