The transfer wrangle between Rangers and Porto over Alfredo Morelos continues.
And from the Portuguese side there appears to be a creeping sense of frustration.
As Lille discovered last summer Ross Wilson and company can be tough negotiators and won't settle for a penny less than what their players are worth.
The French side opted instead for veteran Turkish forward Burak Yilmaz before splashing out on Canadian Jonathan David.
It didn't turn out too badly — LOSC romped to the Ligue 1 title ahead of mega-rich Paris Saint-Germain.
But is that same pattern now repeating itself with the latest Portuguese link?
In the past week two separate reports have suggested the club is now examining plan B.
First came a report in the print version of Porto-based publication Jornal de Noticias, the third-biggest daily in the country.
They claimed that Manchester City's Lukas Nmecha - a 22-year-old striker who has just finished a fourth consecutive loan spell at Anderlecht - is being lined up as a potential alternative despite RB Leipzig appearing to near a deal for the German.
Now a second name has been mentioned across the Stripe.

El Desmarque say Real Sociedad's Willian Jose, who was loaned to Wolves in the second half of last season, is also a target.
He is deeply unhappy at La Real, evidenced by recent comments slamming the club for blocking transfers to Manchester United and Barcelona.
It's claimed Porto also see him as an alternative to Rangers star Morelos but could also secure both in the summer window.
Time will tell as reports swirl of meetings between agent Michael Gorman and the club's long-time president Pinto da Costa.
Whether it's the same old summer story remains to be seen.
