best arsenal can hope for is 3rd place, chelsea will be up there along side man utd, man city i feel have a much stronger team than arsenal. whilst arsenal might just peel away from spurs and attain 4th if not 3rd place in more comfortable fashion
Like I said before, Rooney and Fellaini are not upgrades over what we had before(read Cesc and RVP). They would significantly improve us, but i strongly doubt we'd compete for the league even if we signed them.
