i dont usually sold players after one season.only if there play bad.an example would be:
-i bought kuzmanovic at man city for 11.25mil in season 2009/2010 and sold him for 17.25mil next season 2010/2011.but only becouse he didnt played well.
-i bought merida in 2009 for 1.7mil and sold it in 2011 for 9.75mil +30%
-i bought eduardo from arsenal for 10mil in 2011 and sold it for 15mil next season. and many other players:in my current season i bought 184 players for 257mil and sold 56 players for 422mil.a fair buisness i think:D |
