Town loanees Tom Lawrence and Emyr Huws have been named in the Wales squad for their World Cup qualifier against Serbia in Belgrade on Sunday 11th June.
Blues boss Mick McCarthy has said the Blues have no chance of signing 23-year-old Lawrence, who has spent the season on loan from Leicester on a permanent basis, as he expects him to be playing in the Premier League.
McCarthy hopes to sign Huws, 23, from Cardiff, however, but has played down the chances of re-signing Crystal Palace man Williams, also 23, for a further spell next season.
The squad will take part in a training camp in Portugal prior to the game against the Serbs.
