A 1-0 defeat at the Swabians was Gladbach's third in a row, leaving them three points behind the top six. The Belgian forward believes they must now pull together and get back to winning ways at home to Borussia Dortmund on Matchday 23, then they could put a winning streak together.
"We need to work together, we need to be more aggressive – both in attack and defence," he told bundesliga.com. "If we do that maybe we can win some games. I think if we win one we can win some more, but we need to win the first one; the rest will follow after that."
