Borussia Dortmund's Marco Reus 'has all the time in the world' - Tuchel

Borussia Dortmund attacker Marco Reus has completed his first full training session since returning from injury.

Reus suffered an adductor muscle injury during the DFB-Pokal final in May and coach Thomas Tuchel warned that a first-team return for the Germany international could still be some time away.

"I won't put a sign with a comeback date on him," Tuchel said. "He'll get all the time in the world.

"He trained really well yesterday, and it can certainly continue like that."

Meanwhile, Dortmund have been given an injury boost ahead of their Bundesliga match at bottom club Ingolstadt, with attacker Adrian Ramos and midfielder Gonzalo Castro set to return to the squad.

However, midfielder Shinji Kagawa (illness) and defender Sokratis Papastathopoulos (muscle problem) could miss the trip to Bavaria.

On Tuesday, a depleted Dortmund side won 2-1 at Sporting as Tuchel was fielded the second-youngest XI in Borussia's Champions League history.

He said the win had given his players "a certain level of confidence you can only get through those results."

"I have to pay special compliments to the young lads," he told reporters, adding that the result was "a fantastic experience."
