SportItalia reports the Blaugrana have followed up their reported interest in the Argentine centre-back with an offer.
Romero recently won Copa America with Argentina and could possibly link up with talisman Lionel Messi at Camp Nou next season, as the Catalans have stepped up their chase for the Juventus loanee.
It was reported Barcelona were ready to out-bid Spurs in the battle for the 23-year-old’s services and SportItalia claims the offer has arrived.
Romero moved to Atalanta on a two-year loan deal with an option to buy ahead of last season and impressed at the Gewiss Stadium.
Tottenham have been linked with a move for the former Genoa defender in recent weeks, but the Lilywhites now get competition from the Blaugrana for the 23-year-old.
Romero played 42 competitive games in his first season with Atalanta, including seven appearances in the Champions League.
EXCL 🚨Scende in campo anche il #Barcelona per #Romero. 🇦🇷 Oggi è stata presentata la prima proposta all’#Atalanta. Come anticipato i #blaugrana fanno sul serio per il difensore argentino fortemente richiesto anche dal #Tottenham. #THFC
