Celtic are back in action tomorrow with another Old Firm clash, this time in the Scottish Cup semi-final as the Glasgow rivals face off for a place in the final.

Their last game saw the Bhoys pick up another three points thanks to a blistering 7-0 victory against St. Johnstone at Celtic Park.

As for Rangers, they were in action on Thursday as they took it to extra time to secure their place in the semi-finals of the Europa League, eventually defeating Sporting Braga 3-1 at Ibrox.

Looking ahead to this latest showdown, it seems as though the Hoops have been handed a big injury boost that could have a huge impact on whether or not they secure a win on this occasion.

What's the news?

Speaking ahead of Sunday's clash, Ange Postecoglou revealed in his latest press conference that Hoops midfielder David Turnbull is fit enough to play after picking up a knock in last weekend's league game.

The midfielder had only just come back from a big injury last month before picking up this knock against Saints.

However, now that the Hoops boss has shared this news, it will be a huge weight off a lot of people's shoulders at Parkhead.

Great news for Postecoglou

In terms of what the 22-year-old offers his side, having scored five goals and provided five assists in 21 league appearances this season, the midfielder is a creative and attacking threat from the middle of the pitch.

In those appearances, the former Motherwell star has earned himself an overall WhoScored performance rating of 7.56, making him the highest-rated player currently in the squad.

With Rangers in the way of seeing Celtic make it to the final, having a player who is able to unlock teams by creating goalscoring chances or scoring goals himself such as Turnbull could well be the difference between winning and losing.

To highlight how dangerous the Scottish international is, only Liel Abada (78) has made more shots at goal in the league than Turnbull (69), who has also completed the second-highest number of crosses (141) for the Hoops this season, behind only Jota (190).

Taking this into account, it's safe to say that having the midfield maestro available this weekend is great news for Postecoglou and Celtic's chances of getting to the final.
