LEEDS United playmaker Samu Saiz is set to return after a calf problem for the Whites' trip to Championship strugglers Birmingham tomorrow.

Ronaldo Vieira, though, suffered a knock in the 2-1 win at Burton on Boxing Day and was to face a late fitness test, while Stuart Dallas could be missing again.

Leeds, five points off an automatic promotion spot and in the play-off places after four successive victories, will be needing another three points against a side who prop up the table.

The Blues, without a win in seven league games, will have Sam Gallagher available again after suspension, but Marc Roberts (hamstring), Che Adams (hamstring) and Isaac Vassell (knee) remain sidelined.
