Arsenal physiotherapist Simon Murphy is shadowing Thomas Partey while he is with Ghana.
Ghana meet Mexico in the USA for a friendly this weekend with Partey expected to play.
And he is being given regular treatment while he is away by Murphy, with the Gunners eager for Partey to avoid any setbacks.
Partey missed the beginning of the season after suffering a muscle injury.
Ghana coach Chris Hughton has cleared Murphy to work with Partey while he's with the Black Stars.
