Arsenal are set to move for Barcelona starlet Sergi Samper and will meet his £8.4 million buyout clause, according to Metro.Mundo Deportivo reported that the midfielder could be Wenger's second signing of the summer as he is a long way from breaking into Luis Enrique's first team plans. Players such as Cesc Fabregas, Jon Toral and Hector Bellerin have already made the move from Barcelona's La Masia academy to North London. Arsene Wenger has stated that he needs a potential successor to Mikel Arteta and after missing out on Arturo Vidal this week the 20-year-old could be a perfect fit. Samper is seriously considering Arsenals offer, having grown frustrated playing for Barcelonas B team but the Catalonia-based side would rather agree a loan deal.
