Saturday morning's Chelsea transfer talk news roundup:

Chelsea, Liverpool, Arsenal interested in Weston McKennie?

Premier League clubs in the shape of Chelsea, Liverpool and Arsenal are all reportedly weighing up summer moves for Schalke 04 midfielder Weston McKennie.

The 21-year-old, who has been capped on 19 occasions by the USA, joined Schalke from Dallas in 2017 and has made 91 appearances for the German club in all competitions.

The Texan was again a regular during the 2019-20 campaign, scoring three times and providing one assist in 32 appearances in all competitions but his future at Veltins-Arena is being called into question.

According to CBS Sports, McKennie is expected to leave the Bundesliga this summer, and a number of clubs from England, Spain, France and Germany are keen on a move.

The report claims that Chelsea, Liverpool and Arsenal are all in the hunt for the American, who still has four years left to run on his contract with David Wagner's side.

Schalke are believed to value the central midfielder in the region of £20m.

Chelsea 'want Kai Havertz due to Callum Hudson-Odoi concerns'

Chelsea are reportedly keen to sign Bayer Leverkusen attacker Kai Havertz this summer due to concerns over Callum Hudson-Odoi's development at Stamford Bridge.

Hudson-Odoi penned a new long-term deal with the Blues last September, but the Englishman has struggled to impress this season, scoring just once in 18 Premier League appearances.

According to 90min, the Blues have 'stepped up their pursuit' of Havertz as they are worried by their academy's product perceived lack of progress during the 2019-20 campaign.

Havertz enjoyed an excellent 2019-20 campaign for his German club, scoring 17 times and providing nine assists in 43 appearances in all competitions.

The 21-year-old has less than two years left to run on his contract at BayArena, and it is thought that he will seek pastures new during this summer's transfer window.

Chelsea have already secured deals for Hakim Ziyech and Timo Werner ahead of next season as Frank Lampard looks to build a team capable of challenging for the Premier League title.
