DANNY Wilson, the former Hearts and Rangers centre half who now plays for Colorado Rapids in the United States, is on stand-by for the Scotland game against Mexico a week today, writes Matthew Lindsay.

The national squad’s end-of-season tour of Peru and Mexico has been hit by six call-offs and manager Alex McLeish has been forced to call up four players.

McLeish may need to draft in five-times capped Wilson, who joined MLS club Rapids in January, if he is short of cover following the game in the National Stadium here in Lima on Tuesday evening.

“I think that’s an option for us,” said Scotland coach Peter Grant when asked about the prospect of the 26-year-old joining up with his country.

“We’ll look at it. At this moment in time Johnny Russell is the only one from the MLS who is due to join us. We have Danny Wilson as an option, we are maybe a bit short in the defensive positions.

“That is one we will look at, but we don’t want to bring someone in to stand at the side of the pitch to make up the numbers.”

Meanwhile, Grant has revealed the national squad will sit down and cheer on Liverpool and Scotland left back Andy Robertson in the Champions League final against Real Madrid tonight.

“We will be back from training for that, for sure,” he said. “The boys will all be sitting watching Andy, 100 per cent, because he has a lot of good friends.”
