The England international started his first game in a year at the weekend.
Last January Arsenal knocked bitter rivals Tottenham Hotspur out of the FA Cup, courtesy of a fantastic display from Theo Walcott. He helped Arsenal to a 2-0 lead before disaster seemingly struck. He was stretchered off the field, famously reminding the Spurs fans of the score, with what seemed a serious injury.
It was indeed. He had torn his anterior cruciate ligament in his knee, the injury all professional footballers fear the most.
In the end he spent nine months out before returning to action at the end of last year. He then picked up another injury and it was not until the game against Hull City in the FA Cup at the weekend, 365 days after suffering the initial injury, that Walcott started an Arsenal game again.
He has now been speaking about the issue to Arsenal.com, discussing how he got through the period out of action:
“You need to just come into training with a smile on your face, enjoy it and that’s all you can do.
"I remember when I had one of my injuries before, I came in down in the dumps and rehab seemed to take so much longer.
“You don’t want that, you want to come in and feel like you’re doing something each day. Even though it might be the same things at the start, you benefit when it comes to the end of it.
“I like to work week by week, so I forget about the big picture and the nine months. Week by week, hitting the goals and when you have achieved that, you can feel good about hitting something else.
“When I was first coming in, it was in the afternoon, which is a good thing because I was on crutches and the physios had to deal with the players that were fit at the time.
“I’d see the players go out and that was quite tough. Then I came in during the mornings and just doing that helped me feel I had a place back in the squad, so that was nice.”
Arsenal fans are now hoping he will be back to his best soon, as they begin to boast a fearsome attacking force that could launch them up the Premier League table.
