The 28-year-old impressed in recent seasons, culminating last year with 28 chances created by the England international. Bertrand also launched the highest number of crosses in the Premier League, revealing an attacking zeal which fits ideally with Guardiola’s philosophy.
Napoli defender Faouzi Ghoulam was Guardiola’s preferred option as cover for Mendy but with the Italians refusing negotiate on a deal, the Spaniard is looking closer to home for the solution. Southampton are likely to seek a fee of £28-30m for the left-back.
Bertrand made his name at Chelsea, spending five seasons on loan at a succession of League One and Championship clubs before moving to Aston Villa, then in the Premier League.
He joined the Saints, initially on loan, in a £10m deal in February 2015. Having flirted with the England team since 2012, Bertrand established himself this year as Gareth Southgate’s first-choice left back. His first international goal came in the 4 – 0 win over Malta as England secured their place at next summer’s World Cup.
Southampton identified former defender Luke Shaw, 22, as his replacement, with Manchester United manager Jose Mourinho losing faith in the player.
