Rangers have been busy in the transfer market, with Celtic yet to move.
Rangers have been busy in the transfer market this week, sealing a move for Nikola Katic, with Connor Goldson imminent.
This follows moves for Allan McGregor, Scott Arfield, and Jamie Murphy's move being made permanent, while loaning Ovie Ejaria.
Rivals Celtic meanwhile are yet to act.
Celtic are Scottish football's dominant team, and they are hoping to win an eighth league title in a row next season.
It is because of this that Rangers are showing real urgency, and are desperate to change their own fortunes.
Celtic don't need to react to what Rangers have done, but they do need to act for themselves.
They need to strengthen and keep refreshing their squad to ensure there is no complacency, but most of all they need to think big and work out how to make an impression in Europe.
Celtic's record in the Champions League and Europa League has been poor over the past two seasons - winning just one match.
They need to start showing ambition and spending the television money earned from their European exploits which they have sitting in the bank.
Doing this will help them leave Rangers behind, but their rivals should not be their focus.
Celtic need to act for themselves. There is no sense of urgency at the moment, and while they are not desperate like Rangers, the longer they leave it to strengthen, the more difficult it will be.
