Arsenal are set to intervene in a possible deal between Southampton centre-back Virgil van Dijk and Chelsea.
Arsenal have beaten Manchester City to advance to FA Cup final, where the Gunners will face Chelsea, as the Blues knocked out Tottenham last Saturday.
Antonio Conte has already started to make plans for the next season. The talented Dutchman looks to be one of the main targets for Chelsea alongside Everton striker Romelu Lukaku.
But reportedly Arsenal have joined the race to sign the 25-year-old.
The club is ready to match any wage offered by rival clubs in order to see van Dijk at Arsenal.
Arsene Wenger has tried the 3 at the back system and has been successful with it beating Middlesbrough and Manchester City.
The Southampton man could fit in well in both teams.
