They were getting used to the newly-released Premier League winter ball, which will be in action from this weekend onwards.

Patrick Vieira and his staff were putting the side through their paces at Copers Cope Road – including Academy prospects Tayo Adaramola and Jack Wells-Morrison, who have trained with the first-team multiple times.
It was a chance to put the final touches to the preparations for Saints, with Ebere Eze – who has scored twice in his last three games – central to the action.
