Southampton are closing in on deals for Manchester City goalkeeper Angus Gunn and Borussia Monchengladbach defender Jannik Vestergaard, Press Association Sport understands.

After narrowly avoiding relegation from the Premier League last season, Saints have bolstered their squad with the addition of Stuart Armstrong and Mohamed Elyounoussi.

Mark Hughes’ side are still active in the transfer market, with a permanent deal for highly-rated City goalkeeper Gunn edging towards completion.

The 22-year-old impressed on loan at Norwich last term and was part of England’s World Cup training camp, having been involved with the senior team for the first time last November.

Southampton are also looking to bring in imposing defender Vestergaard from the Bundesliga.

Part of the Denmark squad that reached the last-16 in Russia, the 25-year-old would appear a timely addition to a side yet to bring in a defender since Virgil van Dijk’s world-record move to Liverpool.

Southampton’s only January signing was the club-record deal for Monaco striker Guido Carrillo – a player that has already been shipped out to Leganes on loan.

Dusan Tadic ended his four-year stint at St Mary’s to join Ajax, while questions remain over the future of Fraser Forster and Sofiane Boufal.
