• France coach Galthié furious over loss of pivotal captain

Berrada hopes United can move into the £2bn stadium by the start of the 2030-31 season but said the cost of building it could have an impact, acknowledging that Arsenal and Tottenham struggled to juggle building a ground and fighting at the top.
