The 28-year-old, who netted a super strike to put Manchester United 2-0 up at Crystal Palace, says he is focused now that he has signed his new deal

And Rooney was pleased to be able to finally put the speculation surrounding his future behind him and get back to doing what he does best on the pitch.
"The deal was important. It has more or less been agreed for a month just the fine details needed finishing off. Thankfully it is done," he told Sky Sports.
"I have let my football do the talking. I am happy and settled."
Rooney also felt United deserved their victory - a result that serves as ideal preparation for Tuesday's Champions League last-16 first leg clash with Olympiakos.
"We moved the ball well, maybe could have created more chances. But we controlled the game and knew once we scored the goal we could see the game out. It was a great three points," he continued.
"Whether I signed a new deal or not, I always give 100 per cent.
"We all stick together and hopefully we can bring some success in the near future.
"We have to go on a good run now, hopefully [qualification in the Champions League] will come and if not we'll look to next year."
