Sevilla president Jose Castro has all but ended Arsenal's hopes of signing impressive midfielder Grzegorz Krychowiak on a cut price deal this January after announcing he will not negotiate his sale.
Last month, reports began to circulate that the defensive midfielder was on Arsene Wenger's radar and could be the subject of a bid in January when the transfer window opens.
The midfielder's release clause, reported to be £23.5 million, was thought to be the price Arsenal would have to pay to prise him away from the La Liga side and Jose Castro all but confirmed it to the press on Wednesday.
''We will not negotiate for Krychowiak, nothing is nothing, zero is zero'' Castro was quoted as saying by Marca.
''It's another thing if someone pays the clause, that cannot be avoided, but we will not negotiate anything.''
The warning fired by the Sevilla supremo is unlikely to put Arsenal off if he is, as reported, a key target. However, Castro can safe in the knowledge that the 24-year-old isn't actively seeking a move either.
Speaking to the Super Express, Krychowiak said: ''I don't think about what will happen next month or next year.
''I'm very happy at Sevilla and my future here is not in doubt.''
The Polish international has quickly become a well-respected player in Spain and has impressed with his outstanding range of passing, along with his defensive contribution. He has featured in all Sevilla's La Liga games this season, starting all but one of them.
Although a January exit would be a huge blow for Sevilla and their Champions League aspirations, his arrival at the Emirates could boost the Gunners in their ambition of a top four finish.
