Porto are bracing themselves for summer bids from Manchester City for Fernando and Eliaquim Mangala.
The Premier League side were said to be interested in bringing the duo to England in January, but a move never materialised.
Now, The Manchester Evening News are reporting that a deal could be back on track as Manuel Pellegrini looks to strengthen his title winning squad.
A deal for Managala may be the priority, with Joleon Lescott set to leave the Etihad Stadium this summer, and Martin Demichelis struggling at times this season.
However, it was Fernando who came closest to joining the club in January as City sought a cut prize deal as his contract had been due to expire this summer, but his price-tag may have risen significantly since signing a fresh deal at Porto in February.
The reports in the Manchester Evening News suggest a £16million deal has already been agreed between the two clubs, not even a week after City clinched their second Premier League title.
The Brazilian central midfielder would add competition to an already impressive engine room, joining the likes of Yaya Toure, Fernandinho and Javi Garcia.
Though that deal may be close to completion, any possible transfer of Mangala could be prolonged due to the sheer amount of competition for the Frenchman's signature, with Manchester United being among those credited with an interest.
Despite the reported interest from their biggest rivals, Manchester City are reportedly looking to tie up the deal before the summer and value the defender at £25million.
The 23-year-old has been at Porto since 2011 having come through the ranks at Standard Liege, and his performances in Portugal have impressed many across Europe.
France national team boss Didier Deschamps is among those watching keenly, and has given Mangala the chance to add to his two caps by naming him in his World Cup squad.
Should Manchester City secure their targets, the duo will follow in the footsteps of a number of stars to leave Porto in recent years.
Last summer Joao Moutinho and James Rodriguez both joined Monaco, while the summer of 2011 saw Radamel Falcao make a big money switch to Atletico Madrid.
Though Porto fans will be reluctant to see the pair leave, they'll be keen to see any transfer revenue re-invested into a side who finished third in the Primeira Liga this season having previously won three consecutive titles.
If they're to claim back their crown they'll have to do so under new management, with former Spain under 21 coach Julen Lopetegui taking the reigns in time for next season.
Lopetegui is the third appointment in a year having taken over from interim boss Luis Castro, who in turn replaced Paulo Fonseca.
