Freiburg coach Christian Streich is hoping defender Fallou Diagne will learn an important lesson from his double sending-off this week as he prepares to sit out Sunday's meeting with fellow Europa League contenders Eintracht Frankfurt.

Diagne was shown a red card for giving away a penalty with a foul as the last man in the 5-0 defeat to Borussia Dortmund last weekend.
He then followed that up with an identical challenge, and the same consequences, as Freiburg went down 2-0 at Sevilla in Europe on Thursday.
That proved to be the final straw for Streich.
"The same incident from the same player within the space of five days and that ruins everything that we had planned," he said.
"There are many, many players in our team who fight night and day to improve.
"They are ready to get everything out of themselves, physically and psychologically. It would be desirable if Fallou would also do this quite quickly.
"Fallou is not capable of keeping his concentration over many weeks and months, but that is what we need in Freiburg.
"Now, he is getting his comeuppance for it."
That European disappointment has now been put behind them as they look instead to notch their first league points of the season against an Eintracht side who had more to celebrate on Thursday.
They defeated APOEL Nicosia 3-0 and are on course to reach the knockout stages of the competition, but the focus now returns to the Bundesliga.
"We're delighted to be able to play in Europe and we take it very seriously," said Eintracht coach Armin Veh at a press conference.
"It also helps us when we win because we recover quicker - it's a psychological thing, and it's an art form to be focused when you have to be.
"Unfortunately, we have too few points for the way we have performed so far this season, which is why it would be important to get something now in Freiburg."
Aside from Diagne's enforced absence, both coaches have the same squads available and will gauge any tiredness after their trips on Thursday.
Frankfurt landed just after six in the morning on Friday following a four-and-a-half hour flight back from Cyprus while Freiburg's flight back from Andalusia was delayed on Friday afternoon.
