Dortmund - Buckle in and prepare to enjoy a footballing feast as two of the Bundesliga's most overt proponents of free-flowing attacking play, Borussia Dortmund and Bayer 04 Leverkusen, prepare to face-off at a sold-out Signal Iduna Park on Saturday evening (kick-off 16:30 GMT/ 18:30 CEST).

Allow bundesliga.com to round-up the must-have facts and figures ahead of one of Matchday 1's standout fixtures...

After finishing second and fourth in the league respectively last season, both Dortmund and Leverkusen have their sights set on improving their positions in the standings this time around, and as such will be eager to send a statement of intent to the rest of the Bundesliga this weekend. BVB boss Jürgen Klopp says the aim of the game on Saturday is "not to think about who is further along in their preparations, but who can cause whom as many problems as possible."

Klopp faces a selection headache ahead of the game, with up to ten members of his first-team squad unavailable. Newcomers Adrian Ramos and Dong-Won Ji are definitely out with knocks, while Nuri Sahin, Marcel Schmelzer, Oliver Kirch, Jakub Blaszczykowski and Ilkay Gündogan are all in various stages of recovery. Erik Durm, Roman Weidenfeller and Mats Hummels are doubtful due to a lack of training, but Marco Reus and Ciro Immobile are set to start.

The personnel situation is much more rosy for visiting boss Roger Schmidt, as Saturday could mark a return to action for and Kyriakos Papadopoulos, both of whom have been struggling for fitness of late. That duo aside, however, Schmidt has every member of his playing staff available to him. "We've got a strong squad and all the players are in good shape," the 47-year-old said at his pre-match press conference.

Attacking responsibility was always going to fall more heavily on the shoulders of Reus following the departure of Robert Lewandowski this summer, but Klopp will be looking to the 25-year-old to provide more than just a menace in the final third. If Weidenfeller and new captain Hummels miss out as expected, and with Kevin Großkreutz and Sebastian Kehl on the bench, Reus will be the player the new signings and youngsters such as Matthias Ginter and Durm will look to for on-field leadership.

Werkself striker Stefan Kießling might be banging the goals in for fun right now but the man pulling the strings in the forward department is undoubtedly summer recruit Hakan Calhanoglu. The 20-year-old is endowed with first-rate technique, an enviable ability to both spot and play the decisive pass, and is an expert marksman from set-pieces. He has slotted in smoothly since arriving from Hamburger SV and provided two assists as B04 beat Kobenhavn in their Champions League qualifier on Tuesday.

Jürgen Klopp: "Leverkusen had a quality side to start with but they were very active over the summer break and have put together an even stronger team. Bayer have been an awkward opponent for us in the last few years."

Roger Schmidt: "My players are really looking forward to it. We're starting off with one of the best away games of the season. We're facing a side whose strength is hitting you on the break and in pressing when they don't have the ball."

Dortmund shook off a 4-0 friendly defeat in Liverpool to beat FC Bayern München 2-0 in the Supercup last week before following that up with a comfortable 4-1 win over Stuttgarter Kickers in the DFB Cup first round. Leverkusen are in equally good shape, knocking six past SV Alemannia Waldalgesheim in the cup and coming away with a 3-2 win in their Champions League play-off first leg in Copenhagen.

The statistician that lurks in all of us will not be able to prevent a squeak of delight slipping out upon discovering the symmetry of the sides’ results in head-to-head matches. Both have won 25 of the 70 Bundesliga fixtures contested to date, with 20 draws, while each has triumphed 17 times at home and eight away. Leverkusen won the corresponding match 1-0 last season and in April this year they played out a 2-2 draw at the BayArena
