Manchester City is gaining significant interest in Borussia Dortmund's primary left-back amid the absence of starter Benjamin Mendy.

According to Fichajes, Portuguese defender Raphael Guerreiro is among Manchester City's shortlist for new left-backs. Despite an eventful transfer window by chasing Harry Kane and signing Jack Grealish for £100 million, Pep Guardiola seems keen on adding another player.

Guerreiro is currently on his sixth season with the German squad; he is an effective defender and creative attacker, setting up different playmaking scenarios on the pitch. He has 32 goals to his name, and at the same time, contributing a significant amount of assists throughout his time with Dortmund.

Amid Mendy's absence, Joao Cancelo was tapped to perform at the left-hand side. Naturally, Cancelo is listed as a right-back, but this unprecedented situation requires Guardiola to change. The good news is, Cancelo seems effective in his unorthodox role, but it is still ideal for the club to pursue a natural attacking left-back.

Dortmund boasts a reputation for selling their marquee players, allowing Manchester City to make an offer during the next transfer window in January. However, Guerreiro has been a key player for his German side this season, which can be why Dortmund should hold on.
