Wrong.
You're talking about players sold and bought while he was here.
The sales of the players he brought in and sold later after he left are more than what he spent on the players he brought in.
*sigh*
What? No, it doesn’t work like that. You can’t credit him with someone else selling players 5 years down the line. Have you done a calculation for Moyes and how much profit we made from his signings? Because I assume you’ll want to stop short of crediting him with selling Fellaini and Stones for a net profit of about £70m.
