Your DL, MC and MR is ok
DL will last for 2 maybe 3 seasons.
Mr will last for 3-4 seasons
MC 5-6 seasons.
Gk have only one more season in him.

Rest need to be change asap. Get a good goalie and a great ST with free kick SA and after that try to replace the 3 worst players in your starting 11 every season.
