Young Manchester City duo Emyr Huws and Albert Rusnak have extended their loans at Birmingham City until the end of the season.
Both men moved to the Championship on an initial one-month loan in January, but they have impressed enough to earn a longer stay at St Andrew's.
Huws, 20, has embedded himself into the Blues' starting lineup, starting and completing all four league games since his move to Birmingham.
Rusnak, 19, has started three Championship games and also impressed in the FA Cup encounter against Swansea City last month.
