Striking gambit: Erling Haaland invests in new world chess championship

• ‘There are clear similarities to football,’ says Norwegian

• Compatriot Magnus Carlsen, the world No 1, likely to play

Erling Haaland has become a significant investor in a new world chess championship tour that is expected to star his fellow Norwegian Magnus Carlsen, the Guardian can reveal.

The deal was agreed shortly before Manchester City played at West Ham last Saturday, with Haaland shown on Sky Sports wearing a Norway Chess cap as he entered the London Stadium – without anyone noticing.
