Arsenal are chasing Porto winger Yacine Brahimi.
Correio da Manha says Arsenal are leading the battle for the 27-year-old winger.
However, the deal is said to have stalled due to Porto's £35million price-tag, which they are insisting is met in full.
Porto have already rejected a number of offers from other clubs for Brahimi and the Gunners are similarly reluctant to meet their demands.
They are said to be insisting on the £35m price-tag as they struggle to meet UEFA Financial Fair Play guidelines for next season.
