Man United rejected Arsenal's Gabriel Martinelli after having him on trial

Arsenal FC v Standard Liege: Group F - UEFA Europa League

Arsenal have a future superstar on their hands - and his name is Gabriel Martinelli.

Last week the teenager marked his full debut against Nottingham Forest in the EFL cup with a brace, opening and closing the scoring at the Emirates Stadium.

And tonight, in Arsenal's Europa League clash with Standard Liege, he achieved the same feat in just three first-half minutes.

Martinelli headed home from Kieran Tierney's cross to open the scoring in the 13th minute before latching onto Reiss Nelson's pass and producing a clinical finish in the 16th.

Not bad for an 18-year-old Brazilian who cost just £6m.

Martinelli's second brace in nine days came shortly after Manchester United were held to a 0-0 draw away to AZ Alkmaar.

United failed to register a single shot on target during the 90 minutes, despite having Mason Greenwood and Marcus Rashford both playing.

And to think, the Red Devils actually rejected signing Martinelli in 2017 after having him on trials for two years.

"Between 2015 and 2017 I went there (Man United) four times and trained for about 15 days," Martinelli said in an interview after the Forest game.

"I asked to take a picture with [Patrice] Evra, [Marouane] Fellaini and other guys. [Paul] Pogba knew I was Brazilian and asked if everything was okay with me and where I was playing."

Awkward.

What's worse for United is that Martinelli has scored more goals from open play in nine days (4) than Rashford and Greenwood combined this season (2).

By no means are we suggesting that Martinelli is better than Rashford, but it just goes to show that United missed out on a top talent.

Martinelli later went on to produce a sublime chipped assist for Dani Ceballos to give Arsenal a 4-0 lead. Check it out below.
