The former Spain international hit a sublime dipping volley five minutes before the break at the Allianz Arena to settle the tie, and leave fans, team-mates and opponents alike in awe. However, the FIFA World Cup winner and double UEFA EURO champion told media he had fully intended to pick out the top corner of Christian Mathenia's net.
"There was zero per cent luck," Alonso said after opening his account for the season in the most spectacular style. "I knew that I had hit it well. It was a beautiful goal, and a very important one for us."
'He did it really well'
"I haven't seen such a volley from him, only a low shot from distance," stated Bayern goalkeeper Manuel Neuer. "He did it really well, and we know that he can score goals from long range."
The out-of-this-world strike lit up an otherwise workmanlike display from Pep Guardiola's men, who are looking forward to their Christmas break after an action-packed Hinrunde that has stretched the limits of even their squad.
"The players' condition isn't so great, because we've played a lot of games and have had few opportunities for turnover in recent weeks," said captain Philipp Lahm, whose side will be looking to take their five-point lead at the top of the table into the Winterpause with victory against Hannover on Saturday. "You always look forward to a couple of weeks off, to recover and spend some time with family."
