There's very little difference. What I found, when I looked into it, was that most of our offensive players have less than nine touches on average before losing ball either through a misplaced pass, an unsuccessful touch or being tackled. These were the numbers that I got from WhoScored.com:
Luis Suárez - 4,2 touches per lost ball
Munir - 4,7 touches per lost ball
Ousmane Dembélé - 4,8 touches per lost ball
Lionel Messi - 5,7 touches per lost ball
Philippe Coutinho - 6,8 touches per lost ball
Rafinha - 7,9 touches per lost ball
It's not a number that can mean a whole lot on its own though. Bear in mind that you can also look at how many touches each player on average has before completing an offensive action like a successful dribble, a shot on target, a goal, a key pass and things like that. While Messi may have fewer touches on the ball for every ball he loses than Rafinha, it's important to remember that Messi also has a lot fewer touches on the ball for every dribble or through ball he completes or every goal he scores. You could naturally argue that Rafinha would be better to have on the field if you want to retain possession, but you also have to remember that you lose a lot of creative capacity by choosing Rafinha over Dembélé.
