An unhappy Pep Guardiola complained to the referee for sending off Bastian Schweinsteiger in Bayern Munich's draw with Manchester United, with the coach intimating that Wayne Rooney had dived to get the midfielder a second yellow card.

The incident occurred in the 90th minute of the 1-1 Champions League quarter-final first leg, after Schweingsteiger tackled Rooney. The German was seen twice complaining to the United forward after Carlos Velasco Carballo showed him the red card, and Guardiola appeared to make a diving motion with his right hand.

The Spaniard declined to accuse Rooney after the match but he did not hide his dismay at the sending-off. "I spoke with the referee," he said. "He's a very good referee. He made a very, very good game but it's unfair [this red card]. But it's OK. If you want to win the Champions League you have to solve and overcome everything during the competition. I gave my opinion to the referee, that's all."

Guardiola agreed that he did not think Schweinsteiger, who will now miss the return leg next Wednesday at the Allianz Arena, should have been sent off. "Absolutely not," he said.

For his part the United manager, David Moyes, said: "I think Schweinsteiger trips Wayne up. It's a booking or at least a foul."

United took the lead with Nemanja Vidic's 58th-minute header before Schweinsteiger equalised eight minutes later, but Moyes' side subdued the Champions League holders to keep the tie alive. A visibly upset Guardiola, though, denied he was disappointed with his team's display.
