    Borussia Dortmund welcome back players from Euro 2016  

With four weeks remaining until the start of the Bundesliga, the last remaining players have reported for duty at Borussia Dortmund after Euro 2016.   

For six of them, including recent signings Mario Gotze and Andre Schurrle, the new season began with a performance diagnostic test.

The players are routinely measured and tested on the very first day of training so staff can measure a progression in fitness over the course of a season. 

Andre Schurrle is put through his paces with diagnostic tests on his first day of training 

After returning from Bayern Munich Mario Gotze has his VO2-max taken at Bocham University       It has been almost a month since Gotze and Schurrle suffered elimination from Euro 2016 at the hands of France in the semi-final.

Julien Weigl was joined by his compatriots who arrived at Brackel training centre before heading off to Bocham University for their rigorous tests. 

The latest arrivals went in two group. Firstly Schürrle, Gotze and Raphael Guerreiro, and finally Lukasz Piszczek, Julian Weigl and Joo-Ho Park.

Thomas Tuchel signed Germany international Schurrle for

£24million from Wolfsburg 

Borussia Dortmund will use the results of these tests as

benchmarks for the season After the physical examinations, the players were able to join

up with their team-mates and undertake more conventional

pre-season training with Thomas Tuchel's side.

Dortmund finished second to Bayern Munich in the Bundesliga

and were knocked out of the Europa League by Liverpool in

the quarter-finals.

Bayern Munich again had the edge over their rivals in the DFB-

Pokal cup final, snatching a 4-3 victory on penalties.

Mario Gotze was vilified for leaving to join Bayern Munich but

has returned to Dortmund    Dortmund will be hoping their new signings will make the

difference in the battle for silverware this term and the club

from North-Rhine Westphalia have been busy this transfer

window.

Schurrle joined from Wolfsburg for £24million and Gotze re-

signed with his former team after an unsuccessful spell with

rivals Bayern.

Tuchel has also added Guerreiro, Sebastian Rode, Marc Bartra

and exciting young striker Ousmane Dembele to his ranks as

Dortmund continue their preparations for the start of the

Bundesliga.
