Daniel Sturridge&Wayne Rooneyin normal circumstances I think I'd avoid someone like Berahino like the plague as he's always come across as a bit of a bell. BUT, there isn't a whole load of boss strikers available and like you say, maybe a change will do him good. Every time West Brom have had him on the pitch he's tended to do well for them.
Probably worth a punt as things stand for a small fee.
