It would be a gamble to not take advantage of the status as the european champions and get the best the club can right now, Roman don't want to risk losing out on Champions League like the club very nearly did. Marin, De Bruyne and Sturridge will still only have one injury/suspension or one player from the starting line up getting rested and they would start, considering the amount of games a English team plays a season they will get quite a lot of play time. Lukaku could be screwed quite a bit here though, should maybe be loaned out. The squad needs depth like the other big clubs in premier league and we are getting that.
