Barcelona striker Luis Suarez took a huge bite out of Manchester City in his first game back in England since his Liverpool days.

Suarez, who scored two against Joe Hart in the World Cup, scored two quick goals in the first half of Barcelona's first leg against City at the Etihad to give his club an early 2-0 lead. Suarez has scored as many goals (four) in the Champions League (four games) as he has in La Liga competition (15 games).

Here's his first goal in the 16th minute:

Here's a wicked slide to score goal No. 2 in the 30th minute:

This Suarez fellow is even biting himself. (Suarez usually kisses his wrist and holds up three fingers for his wife and two kids after every score):

UPDATE: Segio Aguero cut Barcelona's lead in half with a goal in the 69th minute, but Gael Clichy was sent off in the 74th minute. City down to 10 men. Messi missed a penalty in the final minute, and Barcelona held on to win the first leg, 2-1.
