The 26-year-old will complete his move to the Scottish champions at the end of the season, when his current deal with the Tannadice club expires.

It was thought that Zaluska would be coming to Glasgow as a replacement for his fellow Pole, whose form has dipped this season amid a series of negative stories about his personal life.

However, asked if he was certain that Boruc would stay on after the summer. Strachan's reply was short and to the point.

"Yes," the Parkhead boss told Radio Clyde.

On the same day that Zaluska's move to Glasgow was confirmed, Czech full-back Milan Misun signed from FK Pribram.

The 18-year-old signed a four-year deal and will officially join when the transfer window opens on January 1.

Misun expressed his delight at moving to the Scottish champions, telling the club's official website: "It is a tremendous honour to sign for a club of Celtic's stature.

"This is a wonderful opportunity and one I will aim to try to make the most of.

"I know that there are some quality players at Celtic and I will need to work extremely hard to break into the first team.

"This is something that I will be giving my all to try and do."

The Hoops take a four-point lead in to Saturday's Old Firm clash at Ibrox and Strachan admits he is focusing on grabbing his fourth Clydesdale Bank Premier League title in succession.

He said: "I do think about it and I want to do it.

"In the third year we were behind and had to come back so you can never really plan on what's coming up.

"But what I do know is that it makes it a lot easier if you have good players around you."
