Last season Firmino started 32 league games, Salah started 34, & Mane 28. Although Sadio was injured for a while which would account for a few of his non-starts. Just looked at United's appearance record in 2007/08. Tevez made 28 starts. Ronaldo also made 28 starts. However he served a 3 match suspension for a red-card offence, & I also believe he missed a couple of games through injury. Rooney only made 23 starts, but he missed a few games early on with a broken foot. Given that you had pretty good back-up with Nani & Saha, I'd say that Ferguson had the squad quality that we didn't have last season. But his main strikeforce of Tevez, Ronaldo, & Rooney - when available - didn't really get rested that much more than our 3 did last season. Despite the lack of rotation, we achieved more points in the 2nd half of the season than we did in the first. & this with us playing 3 games a week on a regular basis. So that flies in the face of this suggestion that our players get tired because of how we play. I do think though, that we'll see Klopp utilise the likes of Shaqiri & Sturridge quite a bit this season. It remains to be seen if Neville is right in the sense that rotation is a major factor in achieving success. I personally believe that players want to play as much as possible, especially if they're in a good run of form.
