Can You Watch Manchester United Train?

I've looked extensively online and it doesn't look like there is a definite date set for an open training session so far this year. I did however find this phone number (0870 442 1994) which you could try calling and asking if they have any further info. Failing that, you could email enquiries@manutd.co.uk and they should be able to help you.

I would say that it would be worth getting on to it quickly as by the looks of it,  the last few years they have had their open training session around this time of the year.
