West Brom boss Tony Pulis insists Albion will rediscover their cutting edge as they look to avoid an upset at Northampton.
The Baggies lost 2-1 at home to Everton on Saturday and go to Sixfields in the EFL Cup on Tuesday aiming to end the hosts' unbeaten run, which stretches back to January.
Albion opened their season with a 1-0 win at Crystal Palace but spurned several chances against the Toffees at the weekend after taking the lead through Gareth McAuley.
They go to the Sky Bet League One newboys for the first time in 21 years and Pulis called on his side to find their shooting boots.
