Marseille, Juventus, Villarreal are reportedly battling for the signature of Nigeria international, Mikel Agu.
French Ligue 1 side Marseille appear to be stepping up their interest for the young Nigerian after they failed to land him in the summer.
Mikel, who is currently on loan to Sporting Braga from Porto had been linked with a transfer to Marseille only for the deal to crumble after he rejected a loan move to France.
According to reports, Marseille were not also prepared to meet the asking price for the 25-year-old.
Marseille sent scouts to spy on Sporting Braga and Vitória Setúbal players during Sunday’s Primeira Liga match at Estádio Municipal de Braga, according to allnigeriasoccer.
Spanish La Liga side Villarreal as well as Italian champions Juventus also had scouts present.
Mikel is currently valued at £1.80 million by transfer market.
The midfielder has spent time on loan at Club Brugge,Vitoria Setubal, Bursaspor and returned for a second spell with Vitoria Setubal in August.
