2 players fighting for every position, we need to show players that if they don't perform they will be dropped. Rotation is key, keeping the players fresh and ready to assault on all four competition's, depth is important too because last September/October although we kept winning it was starting to take its toll before everything exploded in December, and although i wanted Carlo 1 last year to rectify all this some of the tactics and line-up's were so predictable it was laughable. Squad depth is the most important thing for this season, which is why Kalou should stay, his stats for a squad player are pretty impressive tbf.
