Manager Paul Cox is trying to sign a back-up to the 22-year-old in time for the opening game of the season at Sixfields but believes the potential in Studer is 'frightening' and has backed the Swiss to be a big hit.
Northampton signed a goalkeeper of their own this week with the loan cpature of Jordan Archer from Tottenham Hotspur and the Scotland under-21 international is expected to put pressure on Matt Duke for the starting position between the posts.
Archer's arrival has allowed Dean Snedker to join Brackley Town on loan until January while trialist midfielder Lawson D'Ath has earned a short-term deal with the Cobblers with the former Reading man signed until January.
