As underwhelming as the domestic campaign was, Chelsea ended the 2020-21 season at the summit of Europe. It was a considerable overachievement despite their star-studded recruitment in the summer of 2020 with the likes of Kai Havertz, Timo Werner and Thiago Silva. However, as the club learned harshly in their 2013 defence of the Champions League crown, staying atop the peak is a completely different challenge from climbing it.Chopping and changing, the Chelsea wayChange is the only constant in Chelsea's way of life, and this summer will bring opportunities to enhance an already talented squad of players brimming with both youth and experience. In this article we look at some of the top players on Chelsea's radar for the summer transfer window.#5 Adama Traore, Wolverhampton WanderersEverton v Wolverhampton Wanderers - Premier LeagueThomas Tuchel’s three at the back system has created a necessity for versatile wingbacks. As age catches up with Cesar Azpilicueta and Reece James makes the shift to a wide centre-back role, the Blues are in the market for a right-footed wingback. They recently failed in their pursuit of Achraf Hakimi, now of Paris Saint Germain.As a physical and pacy powerhouse, 25-year-old former Barcelona speedster Traore presents a dynamic and direct alternative as a marauding right wingback. The Wolves man also provides extra versatility as he can play as an attacking inside forward.Fabrizo Romano and Matt Law suggest the ongoing pursuit of the current Wolverhampton star presents Chelsea with an opportunity to add a tried and tested Premier League player. He could add vital squad depth for what is sure to be an arduous and imposing campaign.#4 Eduardo Camavinga, RennesParis Saint-Germain v Stade Rennais FC - 2019 Trophée des ChampionsThe 18-year-old Camavinga, having come up against Chelsea in the Champions League, presents a profile in line with the club’s recruitment policy of signing exciting and emerging European talent.Some might argue that the addition of the newly capped French starlet would complicate an already bloated attacking midfield. However, others anticipate the Rennes midfielder will blossom into one of the most talented midfield dynamos of the next generation. Chelsea would be foolish not to place their hat amongst an array of suitors from Europe’s biggest clubs.Club legend and director Petr Cech is said to be a ‘huge fan’ of Camavinga. Reports suggest the director is directly involved in negotiations with his former team Rennes over a deal to sign the player. The club will be hoping Cech can replicate the success of the Eduoard Mendy transfer.
