Chelsea shows interest in Auba ,Cucurella, and Sesko deals

Chelsea is stepping up their search for a striker after making inquiries for Barcelona's Pierre-Emerick Aubameyang and Red Bull Salzburg's Benjamin Sesko; the club is also close to signing full-back Marc Cucurella from Brighton, but no agreement between the clubs has been reached yet. The Blues are keen to add further reinforcements after allowing Romelu Lukaku to re-join Inter Milan on a season-long loan and are assessing their options before making a formal move. Thomas Tuchel has since replaced Frank Lampard as head coach but that interest has endured, with Tuchel enjoying a close relationship with Aubameyang from their time together at Borussia Dortmund. It is unclear at this stage whether Barcelona would be willing to part with Aubameyang, although they have already signed attacking duo Robert Lewandowski and Raphinha this summer and are under pressure to raise funds to register their new players for the upcoming LaLiga season. Aubameyang left Arsenal after falling out with head coach Mikel Arteta over what the club perceived as repeated acts of ill-discipline and poor professionalism. When asked about the situation in December last year, Tuchel said: "I feel sorry for him that he's in trouble. This is not where he should be with his kind of quality and the positive character that he has -- and I still believe in that. "I'm not involved in what's going on at his club now, and for this, I also want to show my respect [to Arsenal] and not be involved and not judge what is right and wrong. "I just have my picture and my relationship with Auba and this is not affected by that." Tuchel's view of Aubameyang is particularly important given his increased influence on Chelsea's transfer strategy following the Todd-Boehly/Clearlake Capital-led takeover of the club. After former director Marina Granovskaia and technical and performance advisor Petr Cech left the club, a reshuffle saw Tuchel take a bigger role in identifying the club's preferred targets. Another option under consideration is Salzburg's Sesko, which has attracted interest from Manchester United among other clubs. The 19-year-old is reportedly available for a fee above €50 million. Aubameyang would be cheaper but the situation for Chelsea is complicated further by ongoing negotiations with Barcelona for several other players. Both Marcos Alonso and Cesar Azpilicueta are keen on moving to the Catalan giants but a fee is yet to be agreed for either player while Chelsea is giving serious consideration to a move for Frenkie de Jong, a long-time target of United's. Chelsea is likely to start their first Premier League game against Brentford this weekend with Kai Havertz leading their attack. Timo Werner is another possible option but his future is increasingly likely to lie elsewhere with former club Red Bull Leipzig among the possible options. Meanwhile, Carney Chukwuemeka has agreed on the terms of a six-year contract at Stamford Bridge and completed his transfer from Aston Villa.
