Sunderland's European tour this summer finishes off with a game against Borussia Dortmund in Austria on the fifth of August.
The game against Thomas Tuchel's side, who finished second in the Bundesliga last season, takes place at the Cashpoint Arena in Austria, the home of SC Rheindorf Altach.
Dortmund posses players such as Henrikh Mkhitaryan, Marco Reus and Pierre-Emerick Aubameyang, though how many of those will still be Borussia players by the time we face one another is anyone's guess.
Kick off is at 7pm local time, and ticket information is expected to be announced shortly. The game will be Sunderland's sixth and final pre-season fixture, ahead of a tough season opener against Pep Guardiola's Manchester City on Saturday 13th of August.
The Cashpoint Arena - otherwise known as Stadion Schnabelholz - is based in Altach, Voralberg and holds 8500 people. SC Rheindorf Altach use the stadium for their games in the Austrian Bundesliga. Voralberg borders Germany, Switzerland and Liechtenstein, so the area is easily accessible.
Why are we playing there? Well, it would appear that Sam Allardyce and the Sunderland players will be spending time in Austria that week after a brief stop in the Lake Geneva area of France, as are Dortmund.
So, with that in mind, it makes sense that both sides meet up and have a game in order to boost fitness ahead of the season starting the following week. On Sunday 14th of August, Dortmund face Bayern Munich in the German Supercup - and, before playing us they have games against Manchester City, Manchester United - so it makes sense that they would play a side that will offer a similar level of competition to Bayern in Sunderland.
