It was quite normal for Sunderland to be considered from the first favorite (if not the absolute) for the direct (rise) rise, coming down from Championship last year and being one of the top names for League 1 the present manages its base position, even if it is in -6 by the champion of Portsmouth, having a less game.
In the last 13 it has been defeated only once and only one is the defeat to which it has so far been forced to seven away, with its record at 4-2-1 and last Saturday's "victim" Shrewsbury, from the headquarters which was relatively comfortable with pure 0-2. The goal to score steadily at each of its outings continued again (13 goals so far, just under two on average per game) and this is something that can also be continued against Doncaster, which in recent times with 10 passive in the last four and 7 goal pass in the last two in.
With such a defensive attitude towards a very good team like Sunderland, it will hardly have luck. In other words, if Fleetwood gives you four and Gillingham three more, why shouldn't Sunderland do something similar? At 3,10 of goalbet the choice - in my eyes - is clear.
