The Sun says he's being lined up to replace Pardew if the under-fire chief West Brom chief gets the boot.
The Baggies were dumped out of the FA Cup by Southampton days after the taxi-gate scandal heaped embarrassment on The Hawthorns.
Rock-bottom Albion also sacked chairman John Williams and chief executive Martin Goodman as the supremos paid the price for bad form.
Pards, 56, has two games to save his job, and 40-year-old ex-Watford chief Silva is the bookies' No1 choice to replace him.
The Portuguese tactician - who left the Hornets amid reports his head had been turned by Everton's advances- is evens to land the post.
Silva failed to keep Hull up last season but performed well at Watford until he was accused of losing focus due to the speculation.
