Tony Pulis is still looking to find the balance in his side despite becoming a centurion and taking charge of his 100th West Bromwich Albion Premier League game last week.

The Baggies switched to a 3-5-2 at Arsenal on Monday night, or as Pulis himself labelled it a 'swivelling four', and the Baggies looked generally solid as they have done all season.

However, goals are at a premium in the West Midlands, and they have only netted five times in six Premier League games so far, despite bringing in Jay Rodriguez from Southampton over the summer - and his promising start.

The Baggies have been hit by a lack of creativity in midfield; their trio of Gareth Barry,  Grzegorz Krychowiak and Jake Livermore at Arsenal proved difficult to break down, but in possession were about as sharp as a Pulis tracksuit.

The Welshman has always had a reputation for solid home form and the Baggies are unbeaten at The Hawthorns this season, albeit a somewhat misleading statistic.

Last time out, they drew a disappointing 0-0 blank against a West Ham side who will practically score your goals for you at the moment - and they stuttered to a draw against Pulis' former side Stoke City too.

As Marco Silva rightly pointed out, set pieces are where the Baggies can make a difference, but have missed the injured Gareth McAuley's presence. He scored six goals from centre-back last season, more than the entire team have managed so far.

Silva would do well to be worried about dead balls given Watford have conceded more goals than any other team from set plays, shipping four from corners and free-kicks in six games.

On the offensive, though, they could cause problems. Assuming West Brom keep the same shape they did at Arsenal, which seems a real possibility, Andre Carrillo and Richarlison could use their pace to good effect in behind the Baggies' wing-backs.

It worked perfectly at Swansea last weekend, before they saw they were getting run ragged and changed shape at half-time, so more of the same would be perfect for the Hornets.

The likelihood is fine margins will shape the game in the West Midlands later today, with goals at a premium and entertainment value also at risk.

However, if Watford can keep up their perfect away record and plant themselves yet further into the record books - then so be it.
