Adam Lallana's £25 million transfer from Southampton to Liverpool must go down as one of the most memorable sell-on success stories in the modern football era after the midfielder's former club Bournemouth netted a mouth-watering £6.25 million from his move to Anfield.
Owing to a 25 per cent sell-on-clause inserted in the deal that took a 12-year-old Lallana from the Cherries to the Saints, the Championship club are now reaping the rewards of a shrewd business decision taken 14 years ago.
Lallana's meteoric rise to stardom started in League One and finished with a place in England's 23-man squad for the World Cup in Brazil this summer, having taken the Premier League by storm with Southampton over the past two seasons.
The club captain took his game to another level under the tutelage of Mauricio Pochettino in 2013/14 and was named in the PFA Team of the Year. Now, he'll have the chance to test himself in the Champions League with Liverpool and challenge for trophies alongside a new set of team-mates that possess talent more on a par with his own.
Brendan Rodgers knows just what a good player he's acquired, and that's why he eventually agreed to pay what was required to get him to Anfield. After turning downing an initial bid of £20 million, Southampton held out for an improved offer knowing that Bournemouth would receive a significant cut of the fee.
Bournemouth's cash windfall will now provide manager Eddie Howe with a realistic opportunity to mount a serious promotion challenge next season, providing the money is reinvested in the first-team squad at Dean Court wisely.
