Morris is quite a differential for sure:
I don't think Luton will win any of the two games they have in GW7 and looks like the worst team in the league together with SU by a distance.
There are no easy fixtures for them and Morris' record before this season is:
34 goals in 104 games in the championship
14 goals in 91 games in League one
0 goals in 15 games in League two
Morris (0,53xG/90 - 0,21npxG/90 - 0,34npxG+A/90 so far this season) has 2 goals (both penalties) in the PL so far this season.
Haaland (1,44 xG/90 - 1,19 npxG/90 - 1,38npxG+A/90 so far this season) has 8 goals and 1 assist in the PL so far this season and got 52 goals last season in the PL, CL and cups and 4 against Wolves, including a hattrick....
Morris has scored 4 braces and 0 hattricks in 287 games (none in the top division) in his entire senior career, Haaland has 6 braces and 5 hattricks in 41 PL games.....
It's not impossible that Morris outscores Haaland in GW7, but is it very likely?
More than 90% of the active FPL-managers will captain Haaland....
I like your team though
