Former Chelsea defender Glen Johnson has urged the Blues to snap up Everton’s out-of-favor defender Lucas Digne in the upcoming winter transfer window. He believes Digne will be a good replacement for the injured Ben Chilwell. The Chelsea left-back has been out of contention for the Blues since suffering a serious knee injury during Chelsea’s 4-0 victory over Juventus on November 23. He is reported to be out for the season after a surgery had to be done this week on his knee.MailOnline Sport@MailSportChelsea eye-up Everton's Lucas Digne with Ben Chilwell sidelined for the SEASON after knee injury trib.al/aNJbekh11:00 AM · Dec 28, 202129627Chelsea eye-up Everton's Lucas Digne with Ben Chilwell sidelined for the SEASON after knee injury trib.al/aNJbekhSpeaking to BoyleSports football, Johnson pointed out that Lucas Digne would be an ideal replacement for the injured Chilwell. He said:“It would be a good signing, he’s a good player. For whatever reason he’s not playing under Rafa [Benitez] at the moment. He’s another realistic target. I’m sure he’d bite your arm off at the opportunity [to play for Chelsea]. He’s not playing as much as he’d like, so that would be a good signing. He can play both sides as well.”He added:“Everton are a good side and they’ve got a decent squad, but Digne’s one of their better players. Rafa has clearly seen something and he prefers the other options. But I am surprised he’s not playing as much.”Digne has made the starting line up 13 times in the Premier League for Everton this season. However, the Frenchman has fallen out of favor with manager Rafael Benitez in recent weeks. This opens the door for a potential swoop by the Blues.Reports from Goal state that the player is available for a loan deal in the January transfer window.
