Wales face Trinidad and Tobago in a friendly at Wrexham on 20 March, four days before hosting Slovakia in their opening Euro 2020 qualifier in Cardiff.

Giggs was at the New York Stadium on Saturday as Vaulks impressed in Rotherham's 3-2 win over Blackburn.

Vaulks, 25, was born on the Wirral and played for Tranmere and Workington before joining Falkirk in 2013.

He joined Championship club Rotherham in 2016 and qualifies for Wales through his mother.
