Mourinho does have a point.
Manchester United coach Jose Mourinho recently took a thinly-veiled swipe at Guardiola, now at Manchester City, by saying Bayern 'bought' titles in Germany before the seasons even kicked off.
"In Germany, Bayern Munich start winning the league in the summer. Every year they buy their rivals' best player. One year it's (Robert) Lewandowski, the next year it is (Mario) Goetze. The next year it is (Mats) Hummels," said Mourinho.
Next season, Germany internationals Niklas Suele and Sebastian Rudy will be joining Bayern from Hoffenheim. But despite their lead, Bayern have looked less than impressive under Guardiola's successor Carlo Ancelotti this season. The Italian has yet to impose his mark on the squad he inherited with only a few changes in personnel.
Guardiola was often a frantic figure on the sidelines, cajoling, urging, encouraging and demanding effort from his Bayern players. Ancelotti is a more relaxed figure, trusting his star-studded line-up to sort out their own problems on the pitch.
Bayern lacked urgency and creativity in Saturday's 2-0 win at strugglers Ingolstadt as Arturo Vidal netted in the 90th minute before Arjen Robben added a second 60 seconds later. "It's Bayern's luck. Or the conviction that we'll end up with goals at the end," said captain Philipp Lahm.
But Ancelotti was clear when asked what he needed to improve before Arsenal. "From what I saw of the (Ingolstadt) game, nothing," he said. "We did well. It will give us lots of courage and self-confidence for Wednesday."
Bayern are on a record 15-match winning streak at home in the Champions League and have won five of their last 10 games against the Gunners. After three straight semi-final exits, the Bavarian giants are desperate to win the Champions League, but defeat to Arsenal -- meaning their first last 16 exit since 2011 -- would be a black mark against Ancelotti.
