The mobile goal for sports grounds is for football games with seven or eleven players. It has a base formed of two bars joined at the back by a crossbar and to bars forming uprights of the correct height when the goal is used for eleven players. A net, which is elastic, is joined to a crossbar at the top. The side bars of the base are of a length corresponding to the correct height for seven-a-side games. The cross bars are removable and can be changed for longer or shorter bars or they can be telescopic.
