Arsenal vs Borussia Dortmund: Jurgen Klopp's team prepare by training in Regent's Park

The German side meet Arsenal at the Emirates Stadium tonight

Borussia Dortmund prepared for tonight's crucial Champions League clash with Arsenal by having a kick-about in Regent's Park.

Photos posted on the club's official Twitter account this afternoon showed Jurgen Klopp's side braving the foggy conditions for a 'pre-warm up' at the Royal Park.

Borussia are top of Group D with 12 points and have already qualified for the knockout round.

Victory at the Emirates tonight will ensure that they progress as group winners, which would secure the German side a second-round tie with a group runner-up.

Arsenal, who lost 2-1 to Manchester United on Saturday, can guarantee their own qualification with a win tonight.

When the sides met in September, Borussia swept the Gunners aside as Ciro Immobile and Pierre-Emerick Aubameyang scored in a 2-0 victory at the Westfalenstadion.

For those wanting to emulate Dortmund's star-studded squad, the nine football pitches at Regent's Park can be hired for £60.00 each.
