Squad sheets: Wigan Athletic v West Bromwich Albion

The showdown between the Premier League's two youngest managers. Yet both have been around long enough to recognise that substance not style is the key. Roberto Martínez's Wigan have lost only three times in 10 fairly polished displays but have still slipped back into the drop zone. "Home games are the diamonds of your season," Martínez, no doubt wary this will be the Latics' eighth in a lop-sided start, said. Meanwhile, Albion's Roberto Di Matteo, at 40 three years Martínez's senior, has seen his newly-promoted team nosedive from fourth to the bottom half in three winless weeks.
