Following Levante’s 4-2 loss to Valencia on 13 September, 27-year-old Campana informed the club that he would like a move.
He also asked Levante president Quico Catalán to lower the €30m asking price to facilitate a transfer.
That development coincided with his agent contacting Leeds, who had Campana on their list, but not as a priority.
At the time, Leeds had an agreement to sign midfielder Michael Cuisance from Bayern Munich.
And according to Superdeporte, Leeds then contacted Levante for the first time on deadline day.
€15m not enough
Leeds chief Victor Orta asked Levante if €15m plus bonuses would be enough for midfield ace Campana.
With very little time for the Levante board to debate it, the answer was no, so Leeds did not make a written offer.
Instead, Marcelo Bielsa’s team refocused their remaining budget on Rennes winger Raphinha, who joined for €15m plus €7m in bonuses.
Campana remains a Levante player, although is admired by Atletico Madrid who have permission to buy a midfielder after losing Thomas Partey to Arsenal.
However, the Rojiblancos can only commit €12.5m to a replacement, which would make any deal for Campana difficult.
As a result, Campana’s inevitable move away from Levante may have to wait until next summer.
The Sevilla youth product won his first cap for Spain last week, playing the second half of their 0-0 draw with Portugal on Wednesday.
