Leeds United manager Marcelo Bielsa

Noel Whelan claims that young striker Sam Greenwood is knocking on the door of the Leeds United first team.

Speaking exclusively to Football Insider assistant editor Russell Edge, the former Leeds hitman and boyhood fan of the club believes the 18-year-old’s form for the under-23s will have certainly caught the eye of Marcelo Bielsa.

The teenager forward has scored five goals in four games for the under-23s but is currently sidelined through injury picked up with England’s youth side.

Whelan admits Greenwood has been hugely impressive since his move from Arsenal over the summer and that his performances will have put him in contention for a place among the senior substitutes.

Whelan told Football Insider: “Probably someone, in my opinion, that might have been pushing for the first-team bench as well.

“I don’t care whether they’re with the under-23s or they’ve been signed from Arsenal and you may not think they’re ready enough, if they’re producing the goods in the under-23s, you know for sure Marcelo Bielsa will be watching and noticing and we’ve seen it beforehand, he’s not scared of putting young players on the bench.

“What he’s already produced for the under-23s will give him good heart that when he comes back he’ll be raring to go again.”

Bielsa currently has Patrick Bamford and Rodrigo as his senior striking options, while Tyler Roberts has also featured as a centre-forward on occasion.

Greenwood has struck up a formidable partnership with fellow summer signing Joe Gelhardt in the under-23s with the pair having contributed to seven goals so far this season.
