Juventus are monitoring Monaco winger Thomas Lemar as a backup, should they fail to agree terms for Douglas Costa.

The talented 21-year-old had a standout season with the French champions last season and is being courted by the likes of Arsenal and Tottenham Hotspur.

Corriere dello Sport report that Costa is still the “primary objective” for the Bianconeri, however they are prepared to pay no more than €30m for a winger this season and Bayern are sticking to their €40m evaluation of the Brazilian.

Liverpool, Barcelona and even Inter are also interested in the 26-year-old, but his primary choice is still Juventus and the cordial relations between Presidents Andrea Agnelli and Karl-Heinz Rummenigge are expected to help facilitate a transfer.

Despite the causes for optimism, the paper reports that Lemar is also being monitored by Juve’s, alongside previous targets including Lazio’s Keita Balde Diao and Fiorentina’s Federico Bernardeschi.

While deals for the latter pair are expected to be complicated due to the less-than-friendly relations with Fiorentina and Lazio, the Frenchman is considered “a pure left-sider” making “perfect” for Max Allegri’s 4-2-3-1 formation which the tactician is expected to continue with next season.
