Inverness have agreed deals with three new players including former Real Madrid goalkeeper Antonio Reguero.
Teenage striker Jason Oswell and right-back David Raven have also agreed moves to the Highland club before the start of pre-season training on Friday.
Boss Terry Butcher said: "They've all agreed to sign and the trio will be challenging for a first team place from day one. Their arrival is a timely boost and we are in advanced negotiations with a view to adding another couple of new recruits next week."
Reguero, 29, came through the youth set-up at the Spanish giants from 1994 to 2002, before graduating to the first team squad.
A serious knee injury hampered his progress at the Bernabeu and spells with Villareal, Orihuela, Alicante and Gandia followed before making the move to the Clydesdale Bank Premier League.
Butcher added: "He wants to play in Scotland and he came up and played a trial at the end of last season and we liked him and he liked Inverness."
Oswell, 19, was previously with Crewe Alexandra, while 27-year-old Raven had a spell at Liverpool, during which time he captained the reserve team.
Butcher said: "Jason's a finisher whose best is yet to come and we're excited about his potential.
"David's got a solid footballing background and though primarily a right-back he gives us the option of playing him anywhere in the back four."
