RANGERS are determined to push through a deal for striker Antonio Colak as discussions continue with PAOK over their first signing of the summer transfer window.

Colak has emerged as a key target for boss Giovanni van Bronckhorst ahead of the new campaign but another day has passed without the move being signed and sealed by all parties in Glasgow and Thessaloniki.

PAOK initially set a price of £2.5million for Colak and the 28-year-old was a half-time introduction for their friendly fixture with Go Ahead Eagles on Wednesday evening as talks progress over a move.

The former Malmo forward is already familiar to the Ibrox crowd after scoring twice as the Swedes knocked Steven Gerrard's side out of the Champions League last August.

A switch to join up with Van Bronckhorst's side has always been an appealing option for Colak and he is seen as an important part of the Dutchman's plans as he prepares for his first full campaign in charge.

Rangers returned to pre-season action at Auchenhowie on Monday and will head to Portugal next week for a training camp before a meeting with Sunderland at the Estadio Municipal de Albufeira on Saturday, July 9.

Former Hearts defender John Souttar is the only new face within the Light Blues ranks so far this term but Van Bronckhorst has seen Ibrox stalwarts Scott Arfield, Steven Davis and Allan McGregor agree deals to remain at the club for another season.

And the four-year contract that Connor Goldson signed earlier this month was a significant boost to Rangers as they gear up for the new Premiership campaign and their Champions League qualifiers in early August.

Now Van Bronckhorst will aim to tie up a deal for Colak as soon as possible as the Croatian internationalist fills the void left by Cedric Itten's departure and seeks to challenge Alfredo Morelos and Kemar Roofe for a starting spot this term.
