The 22 year-old has impressed at Santos since he broke into the first team two seasons ago, attracting interest from a number of European clubs.
And according to reports, Barbosa - the wonderkid dubbed 'the new Neymar' - is ready to consider offers from clubs as he prepares for life away from Brazil.
English giants Chelsea, Man United and Arsenal have all reportedly shown an interest in the striker but could be beaten to his signing by Barcelona.
The Catalan club managed to secure the big money signing from Santos, Neymar, last year and managed to include a 'first-rights' clause for Gabriel in the deal.
The Brazilian U20 international has a buy-out clause of a staggering £40m, but it is believed that Santos will listen to offers around £24m as the youngster's contract expires in 18 month's time.
The Premier League trio may need to meet the £40m buy-out clause if they are to beat Barcelona in the race for his signature.
