Javier Hernandez feels he is in the right shape to help United in the closing stages of the season and to boost his chances of going to the World Cup this summer.
The Mexican striker scored for the second consecutive Saturday when he slid in for a close-range goal against Newcastle, in his first start in the Barclays Premier League since 28 December.
With Robin van Persie and Wayne Rooney sidelined by knee and toe injuries respectively, Hernandez's goalscoring outings come at the perfect time for Reds boss David Moyes as he weighs up his options for the rest of the campaign.
"It's been a very hard season for me, but I'm trying to be very patient, and to work to try to speak on the pitch," he told MUTV after the game on Saturday. "I have nine goals at the moment, so I'll keep working, be patient and speak on the pitch like I always do.
"I'm happy, I played for 90 minutes and it's a long time since I started a game. The World Cup is coming so I need time to prove, whether they give me one minute or 90, that I'm ready and that I want to contribute to the team to help us have a better season."
Moyes will wait to see if Rooney will be fit enough for the Champions League clash with Bayern Munich on Wednesday, but Hernandez is pleased if the manager has some tough choices to make.
"We're all ready to play, and that performance today showed that we are going to make difficult choices for the manager for that next game!"
