Chelsea have been long linked with Borussia Dortmund striker Erling Haaland but could be set to sign his teammate instead.
According to Football London via TribalFootball, Chelsea are interested in signing Borussia Dortmund left-back Raphael Guerreiro this January.
Chelsea boss Thomas Tuchel is keen on signing a left-back this January with Ben Chilwell out for the rest of the season after undergoing a surgery.
Tuchel signed Guerreiro – who can play at full-back or in midfield – from Lorient in 2016 and is looking to bring the Portugal international to Stamford Bridge.
Tuchel is reportedly hoping to use his past connections with Borussia Dortmund to help sign the Portuguese left-back.
Tuchel signed Guerreiro when he was the manager of Dortmund back in 2016 in a deal worth a reported £9.5million, he was mainly deployed as a midfielder but later made the move to left back.
