Warburton said: “Everyone seems to raise their game [against Rangers]. I look at the games Celtic play as well, teams raise their games against Celtic and the following week have a tough fixture. Every week is a tough game, especially at Ibrox. Every game we play is a testing encounter.”
Considering their size in Scottish football, and the role they have played in the history of the game, it is no surprise that teams always want to defeat both Celtic and Rangers.
These fixtures against the two teams become a cup final for their opponents, and picking up a draw - let along a victory - is a scalp for the smaller side.
Rangers and Celtic are expected to win every game they play, and this then becomes even tougher knowing that the opposition are more up for the tie than they usually are, and the pressure must be hard to deal with for players of Rangers and the Bhoys.
Players of both teams have proven they are capable of dealing with this pressure, but there are still times when the occasion seems to get to both clubs.
Rangers lost in the league to Hibs this season when they could have created a clear gap at the top of the Championship table, whilst Celtic have struggled on the European stage with expectation on them to perform and pick up results.
Next season will likely see the return of the famous Old Firm derby, with Celtic and Rangers both set to be in the Premiership again, and this will prove the true giant of the Scottish sport as the games between the old rivals will be the most pressurised fixtures of the league calendar.
