Borussia Dortmund star Mats Hummels has warned his teammates they have to stop leaking goals despite returning to Bundesliga action with a win, ahead of their Europa League showdown with Rangers next month.
Rangers face the German cracks in a glamorous play-off round showdown next month and Dortmund cut the gap at the top of the table to six points behind leaders Bayern Munich after a dramatic comeback win against Eintracht Frankfurt after they returned from their winter break.
They were two goals down, before coming back to win 3-2, but ex-Bayern star Hummels, 33, is concerned at the number of goals they lose, having conceded 28 goals in 18 league games.
And he's urged his colleagues to tighten up. He said: "It is exhausting to keep having to try and fight back to win. Conceding too many goals is a big issue for us.
"We keep losing goals from situations that we shouldn't. We lost three goals in Berlin, three goals in Munich. It's happened far too often to us.
"And what happens when you keep conceding that amount of goals is that you don't always win games.
"Stability in defence should be at the top of our agenda for the next couple of months if we want to win any of the competitions we are in.
"That was a great victory and we showed a brilliant reaction to come back. But we keep struggling on the defensive side of the game."
Rangers travel to Germany for the first leg on February 17 before the return at Ibrox on the 24th.
