Up and running

14 members of the FC Schalke 04 first-team squad took part in training on Thursday, including Julian Draxler and new signing Junior Caicara, who has been described as a "machine" by new head coach Andre Breitenreiter.

Back in town

Douglas Costa "a fighter"

Before his press conference came to an end, Guardiola was asked about new signing Douglas Costa, and the Spaniard is evidently delighted to have him on board:

Crossbar challenge

Could you do better from the edge of the box than the FC Köln players?

Pep glad to be back

Royal Blue welcome

Here’s Breitenreiter and the Schalke squad heading out onto the training ground flanked by scores of well-wishing fans. The mood is optimistic at present, but the new head coach will know he has a job on his hands to improve upon the club's below-par 2014/15 campaign.
