West Brom’s automatic promotion hopes remain in the balance after they were held to a 0-0 draw by Fulham.
Albion’s failure to win offered another Premier League lifeline to Brentford in the race for the top flight.
Slaven Bilic’s side sit second in the Sky Bet Championship, four points clear of the third placed Bees having played a game more with Brentford hosting Preston on Wednesday.
The stalemate all but ended Fulham’s hopes of automatic promotion, although they came closest to winning when Anthony Knockaert hit the bar.
Fourth placed Fulham are likely to have to settle for the play-offs, now sitting five points behind the Baggies with two games to go, but they made the slicker start at The Hawthorns with Sam Johnstone turning Knockaert’s early effort wide.
The Cottagers were the better side in the early stages and came close to an opener after 22 minutes when Knockaert’s cross created havoc.
Ivan Cavaleiro’s header looped over Johnstone and Ahmed Hegazi hacked it clear with Bobby Decordova-Reid ready to pounce for a tap in.
Albion struggled against Fulham’s three-man midfield with their chances limited – Dara O’Shea’s miss-hit cross the only time they had Marek Rodak scrambling.
But they finally got to grips with Scott Parker’s side as Fulham’s early fluency waned although, as a result, it turned into a scrappy affair.
Hal Robson-Kanu flicked on a cross for an unmarked Diangana at the far post and, after turning inside, the West Ham loanee’s shot was deflected wide by Rodak’s outstretched leg.
Harrison Reed then produced a goal-saving challenge on Robson-Kanu and the forward’s dive as he tried to win a late penalty soon after summed up Albion’s desperation.
