Who are the three left-back options for Chelsea to replace injured Ben Chilwell and their market value?

Chelsea and English left wing-back Ben Chilwell who was substituted in last night's 4-0 win over Juventus due to an apparent knee injury is likely to miss the rest of this year at least and possibly the rest of the season. Who are his possible replacements?

Marcos Alonso is the first and natural replacement for the injured Ben Chilwell. The Spaniard started the season as the first choice wing-back on the left before Chilwell deservedly displaced him. He is now a certain starter henceforth till Chilwell recovers. He is worth €15m.

Saul Niguez is another possible replacement for Chilwell. The on-loan midfielder from Atletico Madrid has struggled to hold down a spot in midfield but could be deployed there. His only two games for Atletico Madrid this season were at left wing-back. He is worth €40m.

Emerson Palmieri could be recalled from his loan at French club Olympique Lyon if the injury to Chilwell could rule him out of the season. Emerson was pushed further down the pecking order after Chilwell was signed last season and could get one more chance at reviving his Chelsea career. He is worth €14m.
