Wayne Rooney said he was happy to take over penalty duties at Old Trafford after Manchester United?s 2-1 defeat of Arsenal. Andrei Arshavin capped a brilliant first half by putting Arsenal ahead before Rooney won a penalty when he went down under goalkeeper Manuel Almunia?s challenge, which he scored himself. Abou Diaby turned Ryan Giggs? free-kick into his own net to give the hosts victory in this Barclays Premier League contest, which saw Gunners boss Arsene Wenger sent to the stands late on for his reaction to a disallowed Arsenal goal. Rooney said afterwards: ?No-one really knew who was our penalty taker. Then we got one at Burnley but Michael Carrick unfortunately missed it so from then on I said I?d take them - and thankfully I scored today.? On the match, he continued on Sky Sports News: ?It was a good game. ?I thought we were much better in the second half. Arsenal had a lot of possession in the first half but didn?t really hurt us - apart from the goal. ?The second half we knew we had to be better and thankfully we were. I tried getting on the end of the ball and I?ve done so and the goalkeeper took my legs from me - so I?ve had no option. ?Last season our record against the big teams wasn?t great and Arsenal have started the season well, so we needed to win today. ?Forwards, if they score goals, tend to get man of the match awards - but I think Darren Fletcher was head and shoulders over anyone on the pitch today.?
