FWIW, I've watched a good handful of u21 matches this season and now the season has concluded. Thought I would share my views on each player who has featured.
Paulo Gazzaniga - Todays game featured world class saves and a world class howler. The lad has something. If we sign Steklenberg then I think he should go out on loan and I see no reason why clubs would not be interested.
Dom Gape - Has had to fill in at right back for the latter part of the season and has not been able to show his best. Personally I don't think he will make it with us.
Alfie Jones - Looks a real prospect, nice and composed on the ball, reads the game well. Have been impressed since he made the jump from u18s
Ollie Cook - Doesn't quite have the same composure as Jones. Still has another year at this level to impress, but i'm not sure
Jake Vokins - 15 years old and has a decent left peg. Plenty of time to mature
Harrison Reed - At u21 level you would like to see a little bit more from him on the ball. Can be a little bit sloppy with his passing. Reading of the game and energy levels are always spot on. Either a regular sub or loan move for next season.
Armani Little - He has the passing range and the control and is slowly learning the positional side. Looks a good young talent and will likely be u21 regular next season.
Jake Hesketh - Without checking the stats I would say he has been involved in 3/4 of the goals this season. Always looking for the ball and bright in possession. For me, the player is there we're just waiting for his body to catch up. Would like to see him replace Juanmi in the pecking order.
Josh Sims - Similar to Jake, although younger...in that physically he is at a disadvantage at this level. I think from seeing glimpses of him at u18, its been a disappointing season for him, but there is ability there.
Olufela Olomola - Scored loads of goals for the u18s as a central striker, but has had to adapt to wide role for the u21s, which I don't think is his best role, despite his pace and strength. Ron looks a fan after giving him a spot on the bench recently.
Sam Gallagher - Woeful MK Dons loan spell, poor displays for u21s on his return. Which included a terrible penalty miss and you started to think the game was up, but he has come back fighting and the goals have started to flow. Touch and hold up play are still an issue, but there is something about this lad which is worth persisting with.
Worth noting that Saints have had terrible luck with long term injuries.
Bevis Mugabi, Josh Debayo, Will Wood, Marcus Barnes & Ryan Seager are all long term absences.
Saints current right back situation could well have given Mugabi a chance, had he been able to be fit all season and Seager had just scored his first senior goal on loan at Crewe after another decent goal haul for u21s in the first half of the season.
Isgrove, McQueen, Stephens, Turnbull & McCarthy are all out on loan. I would give McCarthy the biggest chance of getting into the first team. The others may well get permanent moves to teams in the lower leagues.
