The Premier League, Football Association and UEFA are all seeking legal advice over whether pictures of cartoon monkeys promoted online by, among others, former Chelsea captain John Terry infringe copyright law.

As first reported by the Daily Telegraph, the Premier League trophy is trademarked and any commercial use must be agreed with the governing body.
