Champions League: Ko Rnd 1, Leg 1

It's a nightmare start for Arsenal due to a howler from Lukasz Fabianski, who has come in for the injured Manuel Almunia. In the 11th minute, Varela has ample space down the right and slings in a low cross into the six yard box, which Fabianski goes down to claim with no one around him but somehow he manages to deflect the ball into his own net

Arsenal are a bit shell-shocked after going behind and take a good five minutes to spring into life. They force a couple of corners and in the 18th minute a well-worked corner brings dividends as Sol Campbell equalises. The corner comes in from the left which Thomas Vermaelen flicks on to Tomas Rosicky at the far post who heads the ball back across goal where Campbell is on hand to power a header into the net. Arsenal are back in the tie

Campbell celebrates his first goal for Arsenal since rejoining the club. The last goal he scored for the club was also in the Champions League, in the 2006 final against Barcelona

What an eventful night it's turning out to be for Sol Campbell. Five minutes into the second half he is shepherding the ball back to Fabianski when he touches the ball just before the keeper picks it up. The referee awards an indirect free-kick which Porto take quickly and, as the Arsenal defence and Fabianski stand around bemused, Falcao steams in and strokes the ball into the empty net
