“We need to produce a big performance for our supporters and for our future in the competition,” he said.
“The Rangers game taught us a lot. We started very offensively but got caught out.
“It’s vital not to concede first and I hope we’ve learned our lesson.
“We can’t allow Stuttgart as many chances as Valenciennes had.
“They’re a typical German side that love to attack and they’re fighting to stay in the competition.
“With forwards like Gómez, Cacau and Baºtürk around, we’ll need to be on our guard.”
