What to get a boy for their birthday?

ive been going out with my boyfriend for about 4 weeks, and next saturday is his birthday and i have no idea what to get him, he likes football and mostly wears track suits but i only have about �20-30 to spend on him, his ex got him an aftershave set for his birthday last year, so i don't want to get him that, he has all his favorite football teams strips, and he's already getting anew football from his mum & dad, hes not the type of person to listen to music or anything, hes quite sporty though, any ideas? thanks xx
