Portsmouth's record transfer signing is Peter Crouch, who returned to the club from Liverpool for £11m in July 2008. Their record sale is Glen Johnson's move to Liverpool the following summer, for a fee reported in the region of £17.5m — a full-back Portsmouth had signed from Chelsea barely two years earlier for less than a quarter of that price.

The Spending Spree That Won the FA Cup

Crouch's £11m fee capped an extraordinary run of Harry Redknapp-era signings in the same transfer window that won Portsmouth the 2008 FA Cup. Jermain Defoe's £7.5m arrival from Tottenham Hotspur in January 2008 had briefly been the club's record, alongside big-money buys for Sulley Muntari, John Utaka and Lassana Diarra, before Crouch's fee that July pushed the record clear of all of them. It remains Portsmouth's largest-ever outlay on a single player, a relic of the last period before the club's well-documented financial collapse.

A Full-Back Sold for Four Times What He Cost

Glen Johnson's Portsmouth career was defined by a remarkable margin. Signed from Chelsea for around £4m in 2007, he left for Liverpool just two years later for roughly £17.5m, a fee that stands as Portsmouth's biggest-ever sale and dwarfs the return the club ever made on any other outgoing transfer.

Portsmouth signed Glen Johnson for around £4m and sold him for roughly £17.5m two years later — the single most profitable transfer in the club's history, completed just before the entire spending model that produced it collapsed.

Crouch's £11m fee is a useful yardstick against Southampton, Portsmouth's fiercest South Coast rivals, whose own transfer history runs to far larger numbers on both sides of the ledger.
