Chelsea's defensive frailties have seemingly extended to their players out on loan, with young defender Andreas Christensen experiencing a tough initiation in the Bundesliga on Sunday.

Chelsea has conceded five goals in their first two games of the season, including three in Sunday's defeat to Manchester City.

Christensen, on a season-long loan at Borussia Monchengladbach, played the full 90 minutes in defence as his side were thrashed 4-0 by giants Borussia Dortmund, headlined by a Henrikh Mkhitaryan brace.

The 19-year-old Danish defender made one appearance for English champions Chelsea last season.
