All clubs understandably want to maintain their star players.
After all, Southampton would have surely have been relegated in the mid-90s if it wasn’t for Matt Le Tissier, Aston Villa’s short stint as top-four challengers soon diminished once the likes of Gareth Barry and James Milner moved on and Tottenham are shy of a match winner since the world-record departure of Gareth Bale.
This may lead Southampton down the thought process that even if £50m is earned through the sales of Adam Lallana and Luke Shaw, they will struggle to bring in suitable replacements and so any progress made in recent seasons will stall.
Still, Southampton’s home game with Manchester United on the final day could be the last for the club for Lallana and Shaw, with 7/4 the price that the Saints are victorious.
Examples also exist when a club have made an error in turning down a hefty sum for their star names, with far smaller amounts pocketed not too far into the future.
Arsenal, Tottenham, Manchester City and Swansea can all look back and accept that they failed to make the most of the transfer market in the last decade.
Having lost the 2006 Champions League final to Barcelona, Henry was a prime transfer target, with former vice chairman David Dein later revealing that Arsenal turned down two bids of over £50m for their record goalscorer.
Instead, Henry signed a new contract, but only played sparingly in the following season as he suffered a succession of injuries.
He then left for Barcelona for only €24m.
Chelsea were involved in a drawn-out chase of Modric in the summer of 2011, with Tottenham reportedly turning down an offer of £40m for the Croatian pass master on the final day of the window.
Modric did show glimpses of his best for the remainder of the campaign without truly rediscovering the heights of the previous season and in the following summer, he was allowed to join Real Madrid for £33m.
A move back to South America to Corinthians seemed more than possible for Tevez after falling out with Manchester City in the 2010/11 campaign, with reports suggesting an offer of £40m was on the table.
This eventually failed to materialise and Tevez did return to the Man City first team, becoming the first player to score 50 Premier League goals for the club in the process.
He did finally depart Man City in the summer of 2013, with Juventus grabbing themselves a total bargain by landing the Argentine striker for £10m.
Although Michu is still at Swansea, it is unlikely that the club will receive offers in the future in the bracket between £12m and £15m.
This is reportedly what Arsenal were willing to pay last summer after the Spaniard netted 18 goals in his debut Premier League season.
However, two league goals in an injury-disrupted 15 appearances will have seen this figure shrink.
