Robin van Persie feels he's returning to top form at Manchester United.

The striker says a slow start to the season was expected.

"I worked with (Louis) Van Gaal for two years with Holland so I knew how he trained. I knew exactly what to expect.

"He warned me after the World Cup that it would take time for me to get there (top form) but I would be very very fit.

"I am feeling very well now, which I wasn't at the start of the season. So he's right. Every single player, when you are working under Van Gaal, is balancing on the edge - physically and mentally you are concentrating every single minute of the day.

"He expects us to think about football just before we go to bed as well. It is very intense. But I love it and it is a very good way.

"Straight away when he got the job, I realised it would be very intense years but great years as well, because of the way he trains. Every session he puts on there is always an idea and he explains himself well."
