Hard to say as a new head coach is coming in but if I presume it's continuity then he's probably got a very good chance of at least starting the season as first choice on the right. New coach I'd say is likely to move Metcalf into the centre which opens up that slot for him. He was behind Metcalf in the pecking order last season then got injured for pretty much the whole thing so never really got to see him.
He was only able to get on the pitch 4 times for St Pauli last season as he got injured early and only returned on the final day, came on about 80 minutes, got the assist to win the league and got subbed back off for a defender all in the space of about 10 minutes
