It’s not often that a player can command a €100 million minimum fee release clause, but that’s the kind of regard that FC Porto hold striker Hulk in.
Having such a clause inserted in your contract is one thing, but when speculation is rife that teams might actually meet the figure, it’s another situation entirely.
Clubs on the continent are often quick to tie down their best players with long-term contracts and massive sell-on clauses, minimising the potential for any other club across Europe to come in for a prized asset.
But in this particular case, that theory hasn’t come to fruition, and now the 25-year-old could be ready to make a move from the Portuguese Primeira Liga to the English equivalent.
"No offer has been made yet, there is interest but it has not gone beyond that yet. I will start to deal with that next week," agent Teodoro Fonseca told Lancenet.
"There are four other English teams interested in signing him, besides Chelsea.”
Given the financial figures on the table, only the Premier League elite are likely to be considering a move for a player whose stock has risen dramatically over the past four years.
Hulk was a slow starter after breaking onto the scene with Vitoria in his homeland, moving to Japan with Kawasaki Frontale after a brief loan spell at the club.
However, they also sent the Brazilian on loan, firstly to Consadole Sapporo and then Tokyo Verdy. It was in the capital that Hulk really found form, scoring 37 goals in 42 J2 League games.
They would sign him permanently in 2008, but sold him less than 12 months later to FC Porto in a €5.5 million deal. There are ownership issues though, with only half of his rights purchased at the time.
In 2011, a further €13.5 million was paid to tie up 90% of his rights. Despite the potential issues, clubs still appear willing to pay top dollar to secure his services.
The fact that Hulk is also showing interest in a switch away from the Estadio do Dragao is giving hope to the chasing pack, with Porto willing to ‘rethink their stance’ on what figure will be acceptable for the player to leave.
For the player, it’s a case of a big move to try and make his mark on the Brazilian national team, for whom he’s made just nine appearances thus far.
"He dreams of winning it and establishing himself at the national team. In order to achieve that, he has to jump to a more competitive league, we admire the Premier League," his agent added.
“In the end what the player wants will prevail, this is what Porto's board said themselves. Now it depends on the player and those interested in signing him. It will not be easy, there will be some negotiations, but Porto are not saying they will sell him only for €100million."
At a reported €40 million though, Hulk still isn’t cheap.
So what’s all the fuss about? Andre Villas-Boas was certainly a huge fan of the player, getting the very best out of Hulk during his time in charge of the Portistas.
After moving to Stamford Bridge, the Portuguese was verbal in his quest to sign the player, but was pushed out of the door in west London before the opportunity arose for a move.
Last season, Hulk notched 20 goals in 33 league games, whilst the campaign before it was 36 goals in 53 matches as he helped his side to Europa League glory.
With strength and power in abundance, the striker has a cannon of a shot, coupled with a deceptive turn of pace that can leave defenders struggling in his wake.
A fiery temper appears to have been reined in as well, meaning their are few negatives when it comes to what Hulk could offer one of English football's best teams.
With goals in European competition, the player has proved himself at the next level, something that will keep the cheque writers happy if they're going to have to pay a big price for a player.
All the pieces appear to be in place, and all that's left is for a team to agree a price for the player who earned his name because of facial comparisons with Lou Ferrigno - the TV version of The Incredible Hulk.
You won't like this striker when he's angry - or when he's playing for a team that isn't yours. A move surely beckons this summer.
