World Cup 2014: Question marks over Brazil says BBC's Tim Vickery

BBC Sport's South American football reporter Tim Vickery says there are now "question marks hanging over Brazil" following their 0-0 draw with Mexico on Tuesday.

Vickery also believes that Mexico have gained a great deal of "self-respect" after shutting out the hosts in Fortaleza.

Brazil are top of Group A ahead of Mexico on goal difference - with both unbeaten teams on four points after their first two matches.
