Celtic have reportedly agreed deals to sign Paulo Bernardo and Viljami Sinisalo.
The Parkhead club have been heavily linked with both the midfielder and goalkeeper in recent days.
Now, Sky Sports claims transfer fees for the pair have been agreed ahead of summer switches to Scotland.
It's thought Celtic have agreed an initial £3.5m fee for Bernardo to join the club on a permanent contract after spending last season on loan in Glasgow.
However, it's reported add-ons to the deal and personal terms with Bernardo, 22, have yet to be finalised.
Celtic did have an option to sign Bernardo as part of his loan move last season but club chiefs were reluctant to trigger the £6m option and have negotiated a lower upfront cost.
Bernardo is thought to be keen on a return to Celtic after winning a league and Scottish Cup double last season.

Meanwhile, Aston Villa keeper Sinisalo is set to cost Celtic in the region of £1m.
The goalkeeper is expected to sign a long-term deal with the club and join Kasper Schmeichel in a summer move to Parkhead.
The Finland internationalist will join the club as a back-up option to Schmeichel who is also expected to finalise a move to Celtic this summer after leaving Anderlecht.
Sky Sports report Sinisalo will undergo a medical on Tuesday before meeting his new team-mates during the pre-season tour in America.
Schmeichel will replace joe Hart as the new No1 goalkeeper at Cetlic with Sinisalo to be mentored by the experienced stopper. Scott Bain and Benji SIegrist remain under contract at Celtic as further options.
