A failure to make any additions to the squad in the final days of the transfer window has left some Newcastle United fans feeling rather blue over the weekend.

The subsequent announcement of a 25-man squad that includes the inexperienced Jamie Sterry alongside Massadio Haidara and Jack Colback - two players who have failed to impress in recent seasons - did little to boost supporters' emotions.

But a study of the Newcastle squad suggests there is still some depth there, with a number of players ready to step into the first team - so much so that Newcastle could comfortably field two starting XIs.

With Rob Elliot just about clinging on to his first team place, Karl Darlow and Freddie Woodman have been left to do battle as the understudy. Woodman - an England Under-21 international - will surely establish himself as the long-term number 1, but Darlow retains bench duty when fit at the moment.

In defence, three players who have been regulars this term could make a second XI. Javier Manquillo, Jamaal Lascelles and Chancel Mbemba have all benefited from injuries to team-mates, but each player has not looked out of place in the early weeks of the season.

At left-back, meanwhile, Newcastle lack a little depth. However, they do have Jesus Gamez who, as recently as 2015, has started in that role in a Champions League quarter-final.

In the middle of the park, Jonjo Shelvey faces a fight to win his first-team place back and could be joined in a reserve side by Mo Diame - the former Hull City man so far preferred in a deeper role this term.

Henri Saivet struggled as a holding midfielder when he first arrived at Newcastle, but has looked better in recent showings as a creator, where he could be flanked by the impressive young duo of Jacob Murphy and Rolando Aarons.

And, incredibly, Dwight Gayle currently finds himself as Newcastle's third-choice striker. He was the club's top scorer last season but has slipped behind the in-form Aleksandar Mitrovic in the pecking order.

Here's how a second Newcastle XI might look:
