Chelsea have reportedly set their sights on moves for Borussia Dortmund's Erling Braut Haaland or Inter Milan's Romelu Lukaku this summer.
With uncertainty surrounding the futures of Tammy Abraham and Olivier Giroud, Thomas Tuchel could look to bolster his attacking options ahead of the 2021-22 season.
Timo Werner and Kai Havertz both arrived for big-money moves in the summer of 2020, but the ex-Bundesliga attacker have struggled for consistency in the Premier League so far.
According to German outlet Bild, Haaland and former striker Lukaku top Chelsea's wishlist for the summer window, although the former is also wanted by Manchester United, Real Madrid and Barcelona.
Lukaku failed to make a name for himself at Chelsea before leaving for Everton in 2014, but the Blues could supposedly try to lure the 27-year-old back to Stamford Bridge if he calls time on his Inter career.
The Blues have also been tipped to rival Man United and Liverpool for Torino's Andrea Belotti, who could represent a cut-price alternative to Haaland or Lukaku.
