KD did is to find the best combination and also backup. We can't always depends on the same player for the whole season. Maybe it is some rotational testing and to see how the combination will work. But I am glad during those combination we manage to play quite ok compare with previous season. Like previous season, we tried hard to have rotation type but at the end it did screwed up, only one type combination workable. So is important in the early season we can find our touch before gearing up for the rest of the season.
I would say there won't be the best first 11 players, only thing is depends what kind of tactic KD is using. So different tactics we have diff combination. Everything will depends the game strategy. Like yesterday game, we manage to swtich to different way of playing. And it proved us right that we manage to play it well.
I still remember how we struggle so hard for the sake to find the best combination during last season.

Kuyt.... he is just a true loyal servant. You put him anywhere he will tried to do extra miles. He may be striker but he never fail to preform his best when he in others position. I think Kuyt should not be our question for his way of playing, he already earn trust from us. Is same like JC, he may not 100% best defender but the work rate is sure 101%.
I can't blame him not scoring more goals but he did help us contribute goal to others players. Now i can see we won't have a always staring striker, judging from the players we have. We have many option and weapons, is not like previously where tores always play in and out. So he manage to bang many goals. But now I see KD will workout few weapons not solely depends only single player just what we did last time.
Anyway it is a great opening for us, since the time Rafa took over. It had been long 6 years?
