Congratulations to everyone who completed the four-week Nike Football SPARQ Training on Facebook. But are you going to hang up your training shirt and say you’ve done enough? Or are you going to dig deep and keep improving your game? Sir Alex Ferguson is the most successful manager in the history of English football. And the most demanding. Taking home domestic and European trophies in the same season isn’t always enough. Scoring 30 goals in one season isn’t enough. Players need to keep focused, keep on improving. Keep pushing to even greater success. See what he has to say.
