Liverpool keeper Jose Reina and Real Madrid forward Gonzalo Higuain have passed their medicals ahead of moves to Napoli, according to the club's president Aurelio De Laurentiis.
Higuain was strongly linked with Arsenal earlier this month, but Napoli jumped ahead in the race to sign the Argentinian following the sale of Edinson Cavani to Paris St Germain.
Napoli have reportedly agreed a £34.5m fee for Higuain, who will sign a five-year contract at the club.
Jose Reina will be reunited with his former-Liverpool manager Rafael Benitez at Napoli once his season-long loan deal is finalised.
On De Laurentiis's official Twitter account, the Napoli president said: "Higuain and Reina have passed their medicals and will soon join the rest of the group.
"On Monday there will be a big party at the San Paolo. You will be able to get to know the new players and the new shirts."
If the transfers are ratified in time, the pair could feature against Arsenal in the Emirates Cup - a pre-season tournament hosted by the Gunners at the Emirates Stadium.
Arsenal are thought to be on the look-out for a striker this summer, but have turned their attention towards Liverpool forward Luis Suarez after being out-gunned in the race for Higuain.
Napoli have wasted little time reinvesting the £55m windfall received for Cavani. As well as Higuain and Reina, the Serie 'A' club have signed Dries Mertens from PSV Eindhoven, and Raul Albiol and Jose Callejon from Real Madrid.
