Marc Bartra takes to Twitter in attempt to find female Borussia Dortmund fan

Marc Bartra appreciates loyalty.

The Borussia Dortmund defender wants to reward the courage and determination of this supporter who showed up to Dortmund's away draw at Schalke in the famous yellow jersey. A magnificent photograph captured one solitary Dortmund fan sat among at least 100 home supporters but, intent to shout for her side, she proudly showed off her club colours. And Bartra is eager to meet the brave fan in question so that he can offer her his match shirt as a reward for her support. https://twitter.com/MarcBartra/status/848515917822689281 Saturday's game finished 1-1, with Pierre-Emerick Aubameyang's opener cancelled out by a late Thilo Kehrer goal, leaving Dortmund in fourth spot of the Bundesliga table. Bartra, who moved to the Westfalenstadion last summer from Barcelona, has made 23 appearances for Dortmund so far this season and is quickly going about endearing himself to the fanbase. And this latest gesture is only going to help that cause.
