MATCH PREVIEW
Bolton boss Owen Coyle has targeted two wins from their remaining four games to guarantee his side Premier League football for another season, starting at Stoke on Saturday.
I think everybody would agree, 38 points would guarantee you being in the Premier League... The sooner you get that, the better, and that starts on Saturday
Bolton boss Owen Coyle
A few weeks ago Wanderers looked to have hauled themselves out of the relegation mire, but four successive league defeats has seen them slip back into trouble.
Goals remain a major problem for Coyle's men - they have failed to find the back of the net in five of their last six matches and their joint-top scorer is centre-back Gary Cahill with seven.
Stoke, meanwhile, remain on course to achieve manager Tony Pulis's aim of bettering the very creditable 12th-place finish they managed in their debut Premier League campaign.
The Potters are unbeaten in their last three games, but have won just one of their last seven league meetings against Saturday's opponents.
