Arsenal have made a £28.5m bid for Sporting Lisbon midfielder William Carvalho, according to reports in the Sun.
The 23-year-old enhanced his growing reputation with a stellar display in Portugal's win over England in the U21 European Championships on Thursday night.
And the Gunners are now determined to snap up the player they have been tracking for the past two years.
However, there have been suggestions that Arsenal might have to table an offer of Carvalho's £37m release clause to land their man.
Manchester United are believed to be keeping tabs on the situation and could respond if Arsenal have a bid accepted, but Wenger is hoping his impressive offer will help his team beat the Red Devils.
