Chelsea scouts will watch Andreas Christensen on Wednesday night in what they hope will be the young centre back's latest successful audition for a place in the first team back at Stamford Bridge.
Christensen is expected to feature as part of Borussia Monchengladbach's defence when Manchester City come to town on Wednesday night in what might be seen as a test of his Premier League credentials.
The 20-year-old has long-proved his worth at the top level after 18 months in the Bundesliga and is being primed for a role in Antonio Conte's back three next season.
Chelsea will have a keen eye on proceedings in Monchengladbach, as will some of Christensen's many other suitors.
