TEST FOR AMBITION says DARRYL BROADFOOT

THE answer to the above question is simple - not if they have aspirations of a sustained run in the Europa League.

Under normal circumstances, a hefty aggregate loss to Arsenal would demand an extensive rearmament process.

However, a bleak financial landscape for all Scottish clubs puts paid to that notion.

Celtic have rightly prided themselves on fiscal prudence but have been hit by a double-whammy of spending on new players for the manager and losing out on Champions League revenue to which they had become accustomed.

The reality is money may eventually not just talk but swear. Cash-rich vultures from down south are already circling and will inevitably test Celtic's resolve before the transfer window closes on Tuesday.

On the evidence of both legs, Aiden McGeady would attract the greater number of offers, but Scott Brown might be the most expendable. DEPENDS WHO GOES says RONNIE CULLY

PLAYERS will leave Celtic before the transfer window closes on Tuesday. What is yet to be discovered is who they will be, and if they are the men the manager would rather keep.

Tony Mowbray can only hope his phone does not ring with the kind of offer the club would find hard to resist for keystones around whom he wants to build his team.

There is no doubt there is some fat which could be cut from the squad without doing any serious harm. But would any of these players attract any serious money? Unlikely.

So it may yet transpire there is a massive decision to be made on at least one of the top names if the books - now devoid of Champions League income - are to be squared.

Celtic do not want to give any impression they are vulnerable for fear it encourages predators to move in with below-market-value bids.

But their resolve is almost certain to be tested.
