Watch Rangers training as Ryan Jack dishes out Dortmund lessons to James Tavernier and Borna Barisic

Gio van Bronckhorst has been putting his Rangers stars through their paces as they look to finish the job against Borussia Dortmund on Thursday.

And it appears Ryan Jack has taken on the taskmaster role as he was spotted dishing out instructions to his full-backs.

The Ibrox side stunned Europe last week when they ran out at the Westfalenstadion and picked up a commanding 4-2 first leg win.

It leaves them in the driving seat but there is plenty of work to be done yet against the Bundesliga title-chasers.

And Van Bronckhorst has been putting his side through their paces as they look to see the tie out.

The returning Jack was one of their top performers in Dortmund and he seems to have taken the bull by the horns at training too.

At around 54 seconds in the training clip above, the Scotland midfielder can be seen in an intense conversation with Borna Barisic and James Tavernier in which he appears to be instructing the left back on where to aim his crosses.

The clip also shows assistant manager Dave Vos calling the shots as he puts the Ibrox stars through passing and shooting drills to keep them sharp for Thursday's huge game.
