Barcelona have given Arsenal one condition to complete a deal for Denis Suarez, the UK Mirror reports.
The Gunners are favourites to land the Spanish midfielder this month.
Barcelona were playing hardball over a deal, but they seem to have softened their stance over the past week, as Arsenal have stood firm in their bid to sign him.
The Premier League club reportedly favour a loan deal for the midfielder, who would be available for £20million – the price of his release clause.
Arsenal apparently see a temporary deal, for now at least, as a viable option.
But Barcelona want to make money for the player this January.
