Troll Trouble Series by Alan MacDonald, Mark Beech

After a nasty incident with a goat, the Troll family are forced to leave their native Norway and make a new home somewhere else. Unfortunately they choose the quiet suburb of Biddlesden. Faced with the prospect of ‘Baked Beans' for dinner, and the awful spectre of ‘The Shower', things are going to get ugly (and possibly hairy and smelly, too). But worst of all, they have moved next door to the Priddle family. Big mistake.

Ulrik is desperate to be on the school football team, but he doesn't really understand the rules, and his neighbour Warren Priddle certainly isn't about to explain to the troll next door that wellington boots are not the right footwear, and being Fierce and Scaresome will only get you a red card!
