Several members of the Pompey squad were involved for their loan clubs over the weekend.

He was named man-of-the-match in their thumping 5-2 victory over Oxford City at the Recreation Ground.
Mnoga put the home side 2-1 up in the first half, firing home after a corner from Ollie Harfield was not cleared.
The 22-year-old keeper kept a clean sheet on his debut for National League South side Chelmsford City.
He was called into action in the first half, making some key saves that ensured Adam Mills’ strike was enough to earn all three points.
The teenage academy graduate was the second Blues keeper to earn a clean sheet for his loan club on Saturday.
He helped Gosport start their latest Southern League Premier campaign with a 2-0 win over Bracknell Town.
