Lionel Messi is 35 years old and it is fair to say that this is his last chance to shine on the world stage. He has taken part in 4 WC competitions and scored just 6 goals yet is 10/1 jt 3rd fav (Neymar is the other) behind Kane and Mbappe.
Argentina's opener is against Saudi Arabia and if Messi can bag 2 or 3 goals, it will be a decent foundation from which to build on.
Having saved up some of my weekly £5 free bets with Sky, i have used one;
£5 Messi to be top WC scorer @ 10/1 - Sky
