Southampton will step up plans to revamp their attack for next season after guaranteeing their Premier League survival.

High on boss Ralph Hasenhuttl's list of priorities this summer is to bring in up to three new players - two wide men and a central striker - to increase his reliable, attacking options.

Southampton will make a fresh move for Birmingham forward Che Adams who has enjoyed the best season of his career so far, scoring 22 times for Garry Monk's Championship side.

Southampton were keen on £15m-rated Adams in January but Birmingham refused to sell knowing they wouldn't be able to replace him due to the terms of their EFL transfer embargo.

They also anticipated the points deduction that eventually came their way in March and knew Adams' goals would be needed to ensure they stayed up.

Southampton will face competition from Burnley, who also bid for Adams in the winter window, and newly-promoted Norwich.

Charlie Austin is set to leave as part of the overhaul with the striker and Hasenhuttl having mutually agreed it is best time for him to move on for more regular football after three and a half years at St Mary's.

Southampton's other big priority is to recruit a top centre back to become the lynchpin of their defence, something they have been missing since PFA player of the year Virgil van Dijk's £75m departure for Liverpool last January.

A move for a new right-back is also planned if Inter Milan take up their £9.5m option to sign Euro 2016 winner Cedric Soares who has been on loan at the San Siro since January.

Meanwhile, Southampton defender Jannik Vestergaard may need surgery on the groin injury that has kept him out of their last three games.

Southampton are assessing Vestergaard, an £18m signing from Borussia Monchengladbach last summer, before deciding whether he needs an operation.

If Danish centre back Vestergaard does need to go under the knife he is still expected to recover in time to return for the start of pre-season.
