Basically I don't really pay much attention to the depth of the squad for the two teams, but regarding Schalke the 1-3 result is clearly a concern that must be addressed immediately. Looking at the statistics I think Schalke rely on counter-attacking games, implementing this strategy will certainly be a blunder if it doesn't match the squad they have and the coach should consider this. If in the next few matches Schalke still doesn't give good results, it looks like Schalke will stay in the 2nd Bundesliga for much longer.
In my opinion, it is only their first game so I think there are much to see before talking if the Schalke team have the potential to return to 1 Bundesliga or not, but regarding the result that 1-3 score is really a concern that they need to improve, I really think their goalkeeper has done a great job but in terms of the defense department that is the thing they need to strengthen, what I see with the fight against Hamburg but I think eventually given a lot of time Schalke may redefine that and give their all in the next match.
let's see when the first fans of werder bremen arrive here .... we know a few of them.
