The former Celtic striker believes Rangers will need to make additions.
The game will be a massive occasion for Glasgow as Rangers look to show Celtic they have closed the gap between the two sides.
Rangers have secured promotion to the Scottish Premiership for next season after four years out of the top-flight.
One former Celtic player has been discussing Rangers this week. Tony Cascarino spent the 1991-92 season in Glasgow and believes that this weekend will prove a massive indicator to Rangers boss Mark Warburton regarding what he needs for next season.
Cascarino told Sky Sports News HQ yesterday (13/04/2016):
“I think it is a huge test. I don’t believe Rangers can go to the SPL and be a mid-table team. Rangers will be expecting to challenge Celtic. That is the expectation. It’ll be exactly the same for Celtic.
“He’ll be looking at his group of players and thinking ‘what do I need?’ and ‘how close are we to this present Celtic team?’.
“So I think Mark will look at his group and think ‘how well can we do?’.
“I think, long-term, he’ll want to be matching them next year.”
There is no doubt that Rangers fans will be expecting to challenge Celtic for the title next season once back in the Scottish top-flight.
However, the team will still need improvements and as Cascarino points out this weekend’s Old Firm clash will give Warburton a great idea just who he needs to bring in to Ibrox in the summer.
Rangers fans however will just be hoping to get a win over their fiercest rivals this weekend, and book a place in the Scottish Cup final.
