Chelsea are preparing a £7 million bid for CSKA Moscow defender Georgi Schennikov after giving up hope of signing left-back Luke Shaw from Southampton.
According to the Metro, the 18-year-old England international has made clear his desire to join Manchester United, prompting the Blues to turn attention to alternative full-back targets.
Schennikov is highly regarded in Russia and is set to star for Fabio Capello's side at the World Cup in Brazil, prior to sealing a probable move to Stamford Bridge later this summer.
Jose Mourinho has identified the 23-year-old as a long-term replacement for Ashley Cole, and Chelsea will begin negotiations with CSKA Moscow over a prospective transfer in the coming weeks.
Real Madrid and AC Milan have both previously been credited with an interest in signing Schennikov, but Chelsea now looks like the most likely destination for the talented youngster.
Cesar Azpilicueta filled in as a makeshift left-back at times in 2013/14, but is expected to revert to his preferred position on the right side of defence next season.
That could push Branislav Ivanovic into central defence, providing competition for Chelsea's current first-choice pairing of John Terry and Gary Cahill.
And, with Kurt Zouma also set to arrive in west London from Saint Etienne during the summer, Mourinho will certainly have plenty of options to choose from in his back four next term.
