Inverness manager Terry Butcher has agreed deals to sign former Real Madrid goalkeeper Antonio Reguero, teenage striker Jason Oswell and right-back David Rave. All three will complete their moves to the Highland capital before the start of pre-season training tomorrow. 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 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 SPL. Butcher said: "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 was previously with Crewe Alexandra, while 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."
