Pompey are busy preparing for life in the Championship. They won the League One title last season under John Mousinho and went up along with Derby County and Oxford United.
The trio replaced Birmingham City, Huddersfield Town and Rotherham United in the second tier, whilst Sheffield United, Burnley and Luton Town were all relegated from the Premier League, with Leicester City, Ipswich Town and Southampton heading the other way.
Pompey have made a few signings so far this summer and have the chance to land more over the coming weeks. Here is a look at every done deal so far in their league…
