Championship: West Brom v Leeds, Live Sky Sports (KO 5.15)
West Brom boss Slaven Bilic heads into the Championship showdown with Leeds today stressing that a loss of focus could prove fatal for either side.
Leeds have taken over at the top of the table on goal difference, with West Brom failing to win any of their past three matches.
Both sides still have a healthy nine-point lead over third-placed Fulham but, after good winning runs throughout November, neither have been consistent in recent weeks.
"The league is very long and you know you cannot lose the focus because it happens every year," Bilic said. "If you lose the focus, commitment or quality - four or five per cent - then you are gone.
"Sometimes you can get lucky, but normally you pay the price for that."
Leeds' pulsating 5-4 win over Birmingham on Sunday was their first in four games.
But Bilic says Marcelo Bielsa's side have, like Albion, been galvanised by suffering semi-final play-off agony last season.
"They learn from their mistakes, you are double aware, double focused and that's definitely one of the reasons we are there with them and they with us," said Bilic.
