Steve Leigh has warned Baffins Milton Rovers they can't take anything for granted against New College Swindon in their FA Vase second qualifying round tie at the PMC Stadium.
The visitors are without a point and they are bottom of the Hellenic League division one west, having conceded 24 goals in just four games.
Leigh insist his side must approach the game with the right attitude.
The Baffins boss said: ‘We are up against a very young side but must not underestimate them.
‘For both teams it is going into the unknown.
‘Baffins had a good run in the competition last year and we want to better that this time around.
‘If we can repeat our level of performance from Tuesday's 8-0 win against Fleetlands then we have a good chance of progressing.’
The home side are boosted by the return of Jason Parrish up front.
The striker got 45 minutes under his belt in midweek, scoring Baffins’ opening goal.
‘Having Jason in the side gives everyone a huge lift,’ added Leigh.
The hosts are without Blu Boam, Max Davis and Tyler Yates.
