RANGERS have reportedly increased their bid for PAOK striker Antonio Colak.

It's believed that the Ibrox club want to sign the 28-year-old to bolster their attacking options ahead of the new season. 

Now, it appears the Europa League finalists are upping the ante in their pursuit of the Croatian international. 

The Scottish Sun report that Rangers have upped their bid to £2million plus add-ons. 

This follows on from their initial £1.75million vid which was rejected last week.

The Greek outfit are said to be holding out for £2.5million. 

The report states that Colak is happy to head fo Ibrox should a deal be struck between the clubs.

The striker cost PAOK £2.5million from Rijeka back in 2020.

Colak hit a double at Ibrox last August to knock Rangers out of the Champions League qualifiers during a loan spell with Malmo.
