Barcelona has fallen to the Machination of Bayern Munich as the Spanish side was pounded 4-0 in the first semifinal clash of the UEFA Champions League competition this evening.

Thomas Mueller scored twice, Mario Gomez and Arjen Robben had one goal each and Bayern Munich routed Barcelona 4-0 Tuesday night in the first leg of their Champions League semifinal.

Barcelona had few chances, while Bayern used its size to out-muscle the Spanish team.

In a game perhaps signaling a shift in power, Bayern Munich sent Barcelona to its first four-goal defeat since a 4-0 loss to Getafe in the Copa Del Rey semifinals on May 10, 2007.

Mueller scored in the 25th minute and Gomez doubled the lead in the 49th against a defense missing injured center backs Carles Puyol and Javier Mascherano.

Arjen Robben made it 3-0 in the 73rd, and Mueller got his second goal in the 82nd.

The second leg of the tonight’s clash will be played at Camo Nouu on May 1st.

Meanwhile, Borussia Dortmund will be hosting Real Madrid tomorrow for the second semifinal clash of the Champions League.

Four-time world player of the year Lionel Messi, slowed by a hamstring injury, made his first start since April 2 but wasn’t a factor.
