Liam Cooper came into the team to replace Joe Rodon in Leeds’ 3-0 win over Watford on Saturday as the Welshman was suspended after he picked up a red card at Hull City last week.
Luke Ayling also started the game on the bench at Elland Road this weekend with Jamie Shackleton playing as the right-back against the Hornets.
McCormack feels that given the quality of their performance against Watford, Farke should not bring Rodon, Ayling or Archie Gray back into the team right away against Southampton next weekend.
He believes that such a move would send the wrong message to the players while Rodon, Ayling and Gray on the bench against Southampton will maintain the competitive edge of the squad.
The former Whites captain said on BBC Radio Leeds: “If you ask me what I’d do if I was the manager, personally I won’t change a thing.
“It sends out the wrong sort of message, no matter even if you had your best game of the season, these players are still going to come back into the team.
“Whereas, if you keep some of your better players on the bench, sends out a message to the boys who have come into the team, if you come into the team, you play well and then you keep your place.
“That will drive them on.
“Guys like Rodon and Ayling will probably be training next week not expecting to come into the team after that performance.
“But they are experienced enough guys to know that performance is not going to be every week.”
It remains to be seen whether Farke keeps the same eleven when Leeds take on Southampton on Saturday.
