Manchester United defender Luke Shaw admits that he needs to work harder on his fitness after boss Louis van Gaal revealed he would be placed on a special programme.
Shaw joined the Red Devils this summer from Southampton for a fee of £27million, making him the fourth most expensive defender in the world.
However, Van Gaal admitted this week that he was unhappy with the 19-year-old fitness levels and would be placing him on a strict regime.
Van Gaal has adopted the 3-5-2 system with wing-backs which helped Holland to advance to the World Cup semi-finals in Brazil.
The formation requires a lot of work from both wide players to cover the full length of the field and the former Barcelona boss does not feel Shaw is currently capable of playing 90 minutes.
The England international admitted that he was shocked by the step up in level from Southampton to Manchester United and is now fully focussed on hitting his new manager’s targets.
Shaw said: “To play in this formation you have to be really fit. I am fit but I am not at the high level he demands.
“I have got to get fitter to get up and down. It’s something I have got to work on.
“I didn’t come into United thinking it would be much harder. That’s something I think I made a mistake on.
“The focus is now to get fitter and fitter and be flying by the start of the season.”
Manchester United can be backed at 1.40 to claim victory when they host Swansea, who are 6.48 to win, at Old Trafford on the opening day of the Premier League season.
