Charlton’s young guns beat Crawley 2-0 in the Checkatrade Trophy on Tuesday evening.

Ben Reeves and George Lapslie scored their first goals for the club in a dominant display.

Here are five things we learned…

Reeves looks fantastic

The scariest thing about Reeves’ second performance in a Charlton shirt was that he is not even fully fit yet. So, when Karl Robinson deems him fit enough to start in the league, that will be a terrifying sight for opposing teams.

Charlton’s latest summer signing ran the show in the number 10 role, and even looked comfortable on the right wing. He took his goal well with a smart turn and a low, hard finish.

He has a fight on his hands to force his way into the starting eleven given Billy Clarke’s excellent start to the season. But Charlton fans can sleep easy knowing they have two of the top number 10s in League One.

Karlan Ahearne-Grant is playing with confidence

Forced into the first-team at just 17 due to a lack of squad depth in the Championship would've affected any footballer - positively or negatively. Unfortunately, it was the latter for the young forward.

Ahearne-Grant has been on the periphery at the Valley for the past two-and-a-half seasons. But Robinson has put his faith in him after an impressive pre-season, and so far, he is repaying it. He was willing to take on Crawley defenders at any given moment - a sign of his new-found confidence.

The Naby Sarr revival continues

Another game for Sarr, another stellar performance.

The sentence above would not have been typed out two seasons ago. However, Sarr is now part of the Charlton team, and is proving to be extremely good back-up to first-choice centre-halves Jason Pearce and Patrick Bauer.

Sarr has been so good that if Pearce or Bauer were unavailable for selection, not many Addicks supporters would have any qualms about starting him.

The unreliable, error-prone defender we saw two years ago has transformed into a reliable, solid rock at the back. Crawley’s loan striker Ibrahim Meite was bullied by Sarr, who dominated his area.

There are some positives about the Checkatrade Trophy

Often mocked and ridiculed, the Checkatrade Trophy is seen as a burden to most League One clubs.

And with last year’s introduction of Premier League Under-23 teams, it seems to benefit the big boys rather than the League One or Two clubs.

But the competition does have a positive effect on young players. Charlton duo Lapslie and Taylor Maloney made their senior debuts for the club.

So, the Checkatrade Trophy gives youngsters the chance to impress and possibly vie for a first-team place.

A reminder that Charlton’s academy will keep on producing gems

Charlton made 11 changes to the team that beat Rotherham on the weekend, with eight academy graduates lining up against Crawley.

The Red Devils put out a much-changed side, too, but the majority of their players had a wealth of footballing experience.

Charlton’s youngsters had only played a handful of senior games as Aaron Barnes and Reeco Hackett-Fairchild made their first competitive starts for the club.

Despite the difference in experience, the young Addicks eased past Crawley, and could feel disappointed not to have converted more of their 11 shots on goal.

The showing proved why Charlton’s academy is one of the best in the country.
