Well, you never know what happens...
Being asked to give my opinion as of today, I think that the signing of Amedick and Butscher makes sense insofar that we strongly needed players who can lead a team and speak their mind. As far as I know, both players are former captains of their respective teams. Plus Anderson is still recovering from an injury, so it's good to have more defensive players. Moreover, Butscher is able to replace Djakpa, if necessary.
As to Abu, I have no idea. I've never seen him play. If he will be given field time by our manager Veh, good for him. Hopefully it will be good for us as well.
