West Brom boss Tony Mowbray fears only Premiership promotion will keep Manchester City striker Ishmael Miller at the Hawthorns.
Miller maintained his scoring streak with his seventh goal in just 11 appearances since joining on a season's loan from Manchester City - with James Morrison grabbing the winner.
Mowbray wants to sign the 20-year-old permanently and has agreed a fee, but Miller may decide his future lies elsewhere if Albion don't go up.
