According to The Scottish Sun, Rangers are preparing a third bid of around £1 million for Hearts winger Jamie Walker. Rangers have already had two bids - the highest of which was £600,000 - knocked back by the Tynecastle club this summer.
More than two weeks have passed since the second bid was made and Celtic could one-up their Old Firm enemies by capitalising on Pedro Caixinha's indecision.
The Bhoys are in the market for a winger and if Brendan Rodgers can't get Patrick Roberts to re-sign then why wouldn't the Northern Irishman go for Walker?
The 24-year-old scored 15 goals in all competitions last season - including 12 in the Scottish Premiership, three more than Roberts - and he certainly seems to have the pedigree to impress at a club like Celtic.
Question is, would he join them? Why not.
It does not look great for Rangers that Caixinha only upped his original bid by £100,000 and Walker can't have been made to feel valued by such a meagre increase.
If they really wanted him, the Ibrox boss could have signed him by now by meeting Hearts' valuation and Celtic could and should try bringing him to Parkhead.
Walker is the real deal, punctuated by the fact he scored against Premier League side Newcastle United in front of Caixinha on Friday, and the Bhoys should make Rangers pay a steep penalty for their dawdling.
