Chelsea have entered the race to sign RB Leipzig forward Christopher Nkunku.
The French attacker, 24, has been heavily linked with a move to Manchester United this summer, but Sky Germany say Thomas Tuchel is interested in bringing Nkunku to Stamford Bridge.
The Blues are set to undergo a busy summer of transfer activity under prospective new American ownership and strengthening their forward line is a priority for the German boss.
Midfielder Mason Mount is the only Chelsea player to have reached double figures in the league this term, with Kai Havertz and Romelu Lukaku notching only seven goals apiece.
Nkunku meanwhile has enjoyed a stunning campaign at Leipzig, with 34 goals in all competitions firing the Red Bulls to the Europa League semi-finals and fourth place in the German top flight with one Bundesliga game remaining.
United interim boss Ralf Rangnick is a long-term admirer of the Paris Saint-Germain academy graduate meaning the Red Devils are likely to rival the West Londoners in any bidding war.
Leipzig are also unlikely to let their prized asset leave the club without a significant transfer fee, with Nkunku under contract at the Red Bull Arena until 2024.
