Javier Hernandez feels Mexico have plenty to work on going into Tuesday's 2014 FIFA World Cup Brazil™ qualifier against El Salvador, despite starting their Group B campaign with a 3-1 victory over Guyana on Friday.

El Tri were comfortable winners at the Azteca stadium, taking a 3-0 lead inside 51 minutes before defender Hector Moreno put through his own goal to give Guyana a consolation, but Hernandez feels his side should have been celebrating a much bigger margin of victory.

The Manchester United striker told reporters: "The El Salvador match will be difficult, but we still have to think of the Guyana match because there are things to improve upon.

"We should have won by a wider margin. Whether you win, draw or lose, there are always things to improve upon."

The El Salvador match will be difficult, but we still have to think of the Guyana match because there are things to improve upon.

Mexico have claimed convincing victories in their last two meetings with El Salvador, winning 5-0 and 4-1. However, both those triumphs came on home soil and in their last trip to San Salvador, in a qualifier for South Africa 2010, the CONCACAF heavyweights were beaten 2-1. That loss is not playing on coach Jose Manuel de la Torre's mind, though.

He said: "There's no fear about going to El Salvador, just the opposite, we've been planning for the game looking to get a good result."

Rojas aware of high stakes
Tuesday's other Group B match sees Costa Rica travel to Guyana, having been held 2-2 at home by El Salvador in their first game. Costa Rica led 2-0 after just 15 minutes in that match before being pegged back, and coach Jorge Luis Pinto is expected to make a number of changes to his line-up for the visit to Georgetown.

Striker Oscar Rojas told Nacion.com: "We're aware of the big responsibility we have in this match. We cannot change anything from the El Salvador game, but we can correct some mistakes against Guyana."
