JPMorgan has broken its silence over its backing of the now scuppered Super League that caused outrage among football fans across Europe and collapsed within days, saying it "misjudged the deal" and will learn lessons from the incident.

The US investment bank was the sole financial backer for the breakaway league, where a select group of 12 big brand name football teams were promised hundreds of millions of pounds to compete. The bank agreed to underwrite the competition with a €3.25bn loan, with each member receiving an initial payment of between €200m-€300m.
