The additional £4m are seen as ‘achievable’ add-ons, with QPR also having a 20% sell-on clause built into the agreement.
Eze, who scored 14 goals in 46 appearances in the Sky Bet Championship for QPR last season, is now on his way to Palace for a medical where he is also expected to finalise personal terms.
The 22-year-old was left out of QPR’s matchday squad for Saturday afternoon’s friendly with AFC Wimbledon, with the club keen to avoid putting him in an awkward position amid Premier League interest.

While Palace have struck a deal with QPR, Fulham, West Ham and Newcastle have all also expressed interest in signing Eze.
QPR director of football Les Ferdinand, has tipped Eze for an England call-up.
Speaking to journalists after Saturday’s 3-0 win at Loftus Road, manager Mark Warburton indicated Eze would only leave QPR if the club’s valuation was met.
