As the play-off semi-final first leg between Wycombe and Charlton finished in a goalless draw, both teams now prepare for a decisive second leg on Thursday.

Labour Councillor Jo van den Broek expressed concerns about the selling of alcohol at the Post Office, stating that the area is already an 'absolute hotspot for antisocial behaviour,' especially on match days.
