Spain and Argentina prepared to do battle in the World Cup final in New Jersey on Sunday as organisers said they were keeping a close eye on smoke from wildfires in Canada.
Argentina skipper Messi, 39, has been pivotal in dragging the defending champions into Sunday's final in East Rutherford, orchestrating a 2-1 semi-final victory over England with two assists.
The 57-year-old coach has enjoyed a successful reign, winning the World Cup in 2018 and reaching the final in Qatar four years ago, having also won it as a player in 1998.
