Frank de Boer's Crystal Palace are set to make a second bid for Arsenal's Calum Chambers, after seeing their opening bid of around £16m mark rejected last week.
Arsenal are thought to value the 22-year-old right-back at closer to £20m and Frank de Boer has asked that Palace make an improved bid, according to ESPN.
Palace have identified Chambers as one of their top targets this summer as they look to strengthen their defensive options, in order to avoid another relegation dogfight next season.
However Palace face competition from a number of other Premier League sides for Chambers' signature with Everton, West Ham, Southampton and Newcastle also interested in the Arsenal man.
Chambers has been somewhat ruled out of first team plans at the Emirates after being loaned out to Middlesbrough last season.
Chambers signed for The Gunners from Southampton for £16m in 2014, but has since fallen down the pecking order in Arsene Wenger's plans.
The 22-year-old made 36 appearances for Arsenal in his first season but started only two Premier League games in his second campaign at the Emirates,
As a result Arsenal sent him to Teeside for last season's campaign, where Chambers made 25 appearances in the Premier League for Middlesbrough, but saw his loan side relegated to the Championship after finishing 19th.
Nevertheless Chambers seemingly caught the eye of many Premier League scouts due to his performances for Boro and for England's Under-21s, as they reached the semi-finals of the Euros.
Now Chambers is again expected to look for first team football in the Premier League for next season, with Arsenal seemingly not an option.
Chambers would become Franks de Boer's second major signing since taking over at Selhurst Park, with Ruben Loftus-Cheek the only other senior player to have joined so far this summer.
