Arsenal had a blow in their last step to sign another summer after conversations with a player completely stuck, according to reports.
The Gunners have been linked to a large number of players in recent weeks because they want to add to their team in the summer transfer window.
The side of Mikel Arteta tries to improve last season after a third consecutive second place in the Premier League and an impressive run to the semi -final of the Champions League that was terminated by the final winners of the PSG competition.
They have already been stimulated by the signing of Martin Zubimendi – whose transfer of £ 60 million from Real Sociedad was confirmed on Sunday.
However, Arsenal has now suffered a new blow in their attempt to add their team to their team elsewhere.
They have looked at defensive coverage for their first choice center-back combination of William Saliba and Gabriel, who have settled in recent seasons as one of the strongest partnerships of the competition.
But their pursuit of Spain U21 International Cristian Mosquera seems to have gotten in the way of a bump.
According to De Spiegel, conversations between Arsenal and the Valencia defender 'completely stuck' after the LaLiga side has rejected an offer under his release clause -which is assumed to be approximately £ 15 million.
Mosquera, who recently played against England at the U21 European Championships for Spain, is in the last year of his contract, which means that Valencia may still be able to sell him.
They seem reluctant to do this, with Spanish media who report that the club has offered him a contract extension to keep him in the club after this season.
Something will have to give in the Saga, where Mosquera makes all his desire to make it clear to North Londs.
The Mosquera camp has reportedly agreed personal conditions with Arsenal, which could make it even more difficult for Valencia to convince him to stay.
They could still allow him to leave if Arsenal would meet their appreciation of the player, who is said to be more than £ 20 million.
Elsewhere, Arsenal's sports director Andrea Berta reportedly performed the movement of the club for Viktor Gyokeres with face-to-face conversations in Portugal.
They close the sporty Lisbon striker Gyokeres in a deal with a value of a maximum of £ 70 million.
Now the move accelerates, where Berta has poured Portugal to Portugal according to CNN Portugal to sit with the productive attacker.
They report that the former chef of Atletico Madrid flew there last week for discussions with Sporting and it is unclear whether or when he returned.
As Mail Sport reported, Gyokeres came back to the attention after RB Leipzig refused to admit sufficiently in their appreciation by Benjamin Sesko.
