According to Coventry City's club website, you cannot pay on the day for the Tournament at Nuneaton Town this weekend.
However with many refusing to go due to the admission price for both days, Nuneaton have now decided that supporters can now buy tickets for individual matches.
City face Liverpool U23's on Saturday at 2.30pm and Nuneaton on Sunday (5.45pm) and tickets for each game are now £10 adults, £8 concessions or £6 kids. This will be for a specific segregated area of the ground
Tickets are only available from Nuneaton Town FC either by going to their ground between 10am and 5pm if it suits you or by clicking on https://www.ticketor.com/borotournament/upcomingevents?pageid=70668
