Jefferson Lerma is set to join Crystal Palace on a free transfer when his deal at Bournemouth expires in the summer.
The 28-year-old Colombia midfielder has missed just one league match this season, helping Gary O'Neil's side comfortably avoid relegation.
He signed in 2018 from Levante for a fee in the region of £25m.
Crystal Palace will lose two key midfielders - captain Luka Milivojevic and James McArthur - when their deals also expire at the end of the season.
Lerma has a wealth of Premier League and international experience - he has scored 12 goals in 99 top-flight appearances for Bournemouth, playing 183 games for the Cherries, plus one goal in 33 games for Colombia.
