Early elimination in the Champions League quarter-final at the hands of Real Madrid has changed the atmosphere for Bayern Munich and their chief coach Carlo Ancelotti. Winning the German football league and Cup double has become a must for the 57-year-old Italian, and this Wednesday's crunch Cup semi-final against Borussia Dortmund is more of a final.

Winning the double or not will decide how the club and its fans judge the 2016/17 season — one that again ended without them achieving their big dream of securing Europe's biggest crown. Ancelotti made no secret of his expectations saying the season could only be called good if they clinch the double, reports Xinhua news agency.

Captain Philipp Lahm tried to ease the tension by saying that winning the domestic double would make it a "very good season" and bagging only the league title would mean a good one. Considering Bayern have a top-class squad and the expectations before Ancelotti's arrival, it is clear that the double will be seen as a minimum goal.

If he misses out, Ancelotti will be confronted with criticism about his tactical approach and his future plans. Rumours say there is a hefty debate within the club as to whether Ancelotti is the best man to take Bayern forward especially as they intend to concentrate more on developing youngsters. Up until now, Ancelotti has mainly relied on experienced players and has neglected younger talent.

According to several German media reports, Bayern's management is considering to lure Hoffenheim coach Julian Nagelsmann in the near future as the 29-year-old is regarded as one of the biggest coaching talents in Germany for the last decade.

Facing Dortmund in a Cup game will be a major test as the mood at Bayern's opponent is improving after the recent bomb attack — especially as the perpetrator appears to have been caught by the police. The entire club has expressed great relief after what Dortmund coach Thomas Tuchel called "good news" to help the team find its way back to normal life.

While Bayern's mood dipped after a disappointing 2-2 home draw against FSV Mainz 05 in their last league game, Borussia Dortmund feel a warm wind under their wings as the team can work "on a clear mind knowing about the intentions of the attacker" as coach Tuchel put it.

Dortmund also won their last important Bundesliga game 3-2 at Borussia Moenchengladbach and they seem to be well on their way to securing a Champions League qualifying third place.

Tuchel expressed the team's growing confidence ahead of the Bayern Cup semi-final. Dortmund feels ready to spoil Bayern's season, said the head coach. "We'll be doing everything to mess it up for them," Tuchel said.

In contrast to Bayern Munich, Dortmund do not need to win a title to be satisfactory. Qualifying for the Champions League directly via the Bundesliga is enough.

Should Ancelotti manage to win the double, he will most likely get a second attempt to win the Champions League as the club officials like president Uli Hoeness and CEO Karl-Heinz Rummenigge are already planning for the next season.

Looking for an additional attacker and a right back, Bayern are thinking about two players from the English Premier League, namely Arsenal's 28-year-old forward Alexis Sanchez and Tottenham's 26-year-old Kyle Walker.

So far, Bayern have given contracts to TSG Hoffenheim's 21-year-old central defender Niklas Suele and teammate and midfielder Sebastian Rudy. Suele is a €20 million ($21.8 million) investment.

Ancelotti is aware of his club's current turbulence and is looking to get over the recent Champions League exit. The Italian said it was a shock for his team to be knocked out and it is hard to concentrate on new goals such as the double in Germany.

Failure to achieve its goals would open the doors for a substantial crisis for Bayern and Ancelotti.

The game against Dortmund is Ancelotti's chance to reach the finish line without major damage. Looking at Bayern's German Cup statistics, things seem give reason for optimism. Bayern have only lost two of their last 33 Cup games. But there again they were both defeats against Borussia Dortmund.
