Marc-Andre ter Stegen has warned his Barcelona team-mates of the dangers posed by opponents Borussia Dortmund in their Champions League opener on Tuesday night.

The German goalkeeper says he hopes to start the competition right, especially after Barca’s embarrassing semi-final exit at the hands of eventual champions Liverpool last season.

Beaten 4-3 after losing the Anfield leg 4-0 having won 3-0 at the Camp Nou, Ernesto Valverde’s men are in Group F this time round – and start their campaign with a tough tie at free-scoring Dortmund.

There are doubts about Lionel Messi’s fitness, and hopes among many that the scintillating Ansu Fati starts. If he does, at the age of 16, he will become the youngest Barca starter in their Champions League history.

“It’s clearly not easy to play here in Dortmund, last time I was here with Borussia Moenchengladbach we were made to suffer by BVB,” said Ter Stegen.

“But this time we will try to win the match. The competition begins now and we hope to start it right, with a successful first game to enter the group matches in good spirits.”
