Zenit St Petersburg are preparing to table a £9million bid this week for Celtic midfielder Tom Rogic.

It is understood that Celtic are unwilling to tolerate offers for the Australian internationalist who still has four years on his contract for anything less than £15m. There is also substantial interest in the midfielder from an English Premier League side, with Celtic’s resolve set to be tested in the coming days with a formal bid anticipated from Zenit.

Rogic came to the attention of Zenit when Celtic played against them in the Europa League in February 2018. Celtic were eliminated after a 3-1 defeat but it’s understood that Rogic has been on the radar of the Russian side for the last eighteen months.

On the hunt for a number 10, Rogic has been identified as the player the Russians wish to add to their squad but Celtic are reluctant to sell.

Rogic did not travel with Celtic to Austria for pre-season but is understood to be on track to be fully fit for the start of the season.

The player’s preference is understood to be for a move to the English Premier League but with a lucrative contract set to be put before him from Zenit he could have a major decision to make.
