Mexico coach Miguel Herrera has revealed he will use Saturday's friendly with Ecuador as another chance to finalise his starting line-up for his side's World Cup opener with Cameroon.
Mexico's preparations have already begun in impressive style, with a 3-0 triumph over Israel on Thursday, and Bosnia-Herzegovina and Portugal await before their campaign gets underway against Cameroon on June 13.
After the win over Israel, which acted as a farewell for the retiring Cuauhtemoc Blanco, Herrera stated that there was still room for improvement and also urged caution on midfielder Hector Herrera, who sat out Thursday's match.
"There are still distractions," he said. "We must continue this co-ordination, the movements that we want are things that we will be correcting.
"We hope that when we get to Dallas to train, [Herrera] arrives at the stadium having recovered well, but there is no hurry if the doctor says that he is not 100 per cent.
"We hope that on Saturday we have a full team, then we can begin to see others and begin to make decisions about who are going to be the core of the team."
Ecuador were last in action almost two weeks ago, when Jefferson Montero's goal was cancelled out by a glorious volley from Robin van Persie in a 1-1 draw with the Netherlands in Amsterdam.
Unlike Mexico, Ecuador's final 23-man party is yet to be announced, with head coach Reinaldo Rueda still waiting to decide on who will make the cut before Fifa's final deadline of June 2.
They have been drawn in Group E along with Switzerland, France and Honduras for the finals, and will take on England on June 4 before their campaign begins in earnest against the Swiss 11 days later.
