The 26-year-old has been a key player for Leeds in recent campaigns and he has also managed to establish himself on the international stage.
Phillips is a favourite at Elland Road and has two years remaining on his current deal at the club, but his future is under the scanner as he has transfer interest from several top clubs.
Ligue 1 giants Paris Saint-Germain have the Leeds star on their transfer radar while Premier League champions Manchester City have identified him as their top target to replace Fernandinho in midfield.
And the Whites are now braced for the Citizens to make concrete moves to snare away Phillips by tabling an offer for him.
Leeds are keen to keep hold of Phillips in their ranks and are tipped to demand a significant fee to allow him to leave this summer.
Both Manchester City and PSG can offer the midfielder Champions League football, while Leeds will be looking to establish themselves as a top flight side next season having narrowly avoided relegation last term.
Leeds have bolstered their midfield by bringing in Marc Roca in the ongoing window but they see him as support for Phillips, and not as a replacement for him.
