Many reds will have fond memories of United's last tip to south east Germany, when United competed in the four-team Audi Cup tournament last July.
Those who went speak of a carnival-like atmosphere with Bayern, Milan and even Boca Juniors fans joining in a celebration of booze and barbecues with reds over for some pre-season fun.
They got a chance to see the new (ish) Allianz Arena in full swing.
The capacity is 69,901 providing UEFA allow standing and United would get about 4,000 tickets - possibly more.
The city is well worth a visit. The centre has some excellent bars and some worthwhile tourist spots like the town hall and two of the world's most grand churches closeby.
And, of course, there is the second spiritual home of every red - the Munich Memorial - a great chance to pay your respects to the Busby Babes.
