I'm quiet certain it will be an issue. Neither Kolarov or Cissokho will be happy to sit on the bench for the vast majority of the season. If Cissokho does sign and replaces Kolarov then he will probably be gone by xmass meaning we are still in the exact same situation as now. I admit that we need more cover at left back but a 15mil specialist left back is not what you sign for cover.
Kolarov had 20 games at left back last season, Zaba 13 and all the other 7. So that is 40 games on the left. This will probably rise to 55 - 60 this season. Assuming kids will be given 5-10 that leaves 45 to 55 games to share between 2 players at the most. Injury rotation and the like will see the get 25/20 split or a 30/20 split if Cissohko proves to be distinctly superior. This assuming neither gets injured, which is unlikely.
Trust me there will be no issues. This happens at big clubs all the time. The biggest stars start a lot of games and the mid-range stars share time. Unless they want to play at midlevel clubs, there will be no problem. Neither is world class. Both are quite decent. They will share games as coach sees fit, and will be fine with it.
