Premier League arch-rivals Liverpool and Manchester United have both frequently been tipped to enter the bidding race, whilst amongst the plethora of guessed valuations in the English newspapers, The Sun claim that Sevilla are willing to sell Bacca for £14 million, whilst suggesting Tottenham Hotspur and Newcastle United are both ready to swoop at that price.
A new story every day it seems, although the realities are somewhat different. Both in terms of valuation and how willing Sevilla are to sell their leading striker, because the truth is, doing so couldn't be any further from their minds.
Part of the problem is given the sales Sevilla have made over recent summers, there's a misconceived idea amongst predominantly the English press, that they're a club struggling economically. That isn't true in the slightest.
Speaking with the official Sevilla FC radio station, sporting director Monchi explained clearly: "We don't have any economic obligation to sell, because our accounts are healthy, plus with the added economic injection of playing in the Champions League next season, even more so."
As for the inevitable interest in players such as Bacca, there acknowledgement that is inevitable, but he also pointed out: "The guarantee of playing in the Champions League will be noted at an economic level, by our stature, and how motivated players will be to come, or to reject offers from elsewhere."
With those words, the Sevilla chief has underlined that his club are now in an excellent position not only to strengthen, ahead of competing in the elite European competition, but also to successfully ward off interest from the wealthier clubs of the Premier League, for their current crop of stars.
Indeed, the only thing that could lead to Bacca leaving Sevilla this summer, is if he requests to do so. That seems entirely unlikely, given how settled he is in the Andaluz city, along with repeatedly having declared his loyalty to the club.
Should that change however, having raised the hypothetical question with my sources at Sevilla, they assured me the club would stand firm on their €30 million clause valuation (roughly £21.5 million), which formed an integral part of a new contract he signed just last September. A contract which ties the Colombian international to the club until June 2018.
Questioned at the time about whether there had been help from his agents, over the new deal, Bacca first gave a puzzled look, then responded: "I don't have agents. The only agent for me is God."
He also explained: "Many clubs have called the president of Sevilla and Monchi, but my primary intention is to stay at Sevilla. All we wanted was to improve the economic side of things. Anyone who wants me, must now pay the clause value. My family is very happy here and I am too."
Indeed, the situation seems to remain the same for the player. Perhaps a move to Manchester United might be tempting, given they're also in the Champions League next season, and might not bat an eyelid at stumping up that €30 million.
But would clubs such as Liverpool, Tottenham or Newcastle pay that much, for a player who might regard such moves as a sideways step at best, or a downward step at worst? Right now, it doesn't seem at all likely.
