Argentine’s mercurial striker Lionel Messi assured his disappointed fans worldwide that the team is not sweating over their shock 1-2 defeat to Saudi Arabia in the Group C World Cup opener at the Lusail Stadium on Tuesday.

Goals from Saudi’s Saleh Al-Sehri and the skillful Salem Al Dawsari saw the Gulf nation register one of the biggest upsets in World Cup football after Messi had scored off an early penalty to give the two-time champions the lead.
