Best route from King’s Cross to London Stadium for Soccer Aid

[Whereandwhen]

Going to Soccer Aid at the London stadium on Sunday. Staying near Kings Cross Stadium. Not sure whether to travel there and back by tube or go via St Pancras to Stratford International. Any advice on what might work best (assume very busy tubes etc) appreciated.

I don’t think it will be too busy but I would suggest downloading Citymapper and that will give you the best/quickest option on the day, with real time data on what’s running etc
