Chelsea are ready to battle Manchester United for Ben Chilwell next summer.

The Blues have decided that neither Marcos Alonso and Emerson Palmieri are long-term options at left-back.

As such, the club's scouts have been told to look at left-backs from around the world.

One name already being considered is England international Chilwell, according to 90min.

Manchester City and Tottenham Hotspur are also interested in the 22-year-old.

The Blues have listed Basel's Paraguayan star Blás Riveros as a cheaper alternative should a bidding war ensue over Chilwell.
