Wigan manager Roberto Martinez believes only a perfect performance will be good enough to beat West Brom as his side begin their fight for Barclays Premier League survival.
The Latics are bottom of the table with 10 games remaining having won only one game at home this season. Saturday they will face a West Brom side who have one of the best away records, with their form away from the Hawthorns only eclipsed by league leaders Manchester United and title contenders Manchester City.
"Manchester United, Manchester City and West Brom - those are the best top three away records in the league so that shows you away from home West Brom are a tough team to play," Martinez said.
