Premier League duo Manchester City and Arsenal are interested in signing Monaco defender Fabinho with reports in France suggesting both teams will battle each other for his signature in the summer. The 20-year-old defender is having a good season on loan at French club AS Monaco and will more than likely make a big summer move from Portoguese club Rio Ave. According to Le 10 Sport, Arsenal and Manchester City are both watching the Brazilian youngster and will both be prepared to make a bid when he is made available at the end of the season.
