Charlton ended 2017 with a gutsy display against Wigan on Friday.

Latics captain Sam Morsy nearly nicked three points in second-half injury-time when his deflected strike hit the post.

And Karlan Ahearne-Grant had two chances to give Charlton the lead, but failed to hit the target from close-range.

Here are five things we learned…

Charlton showed heart and desire

Wigan were unbeaten in six leagues games. Charlton were winless in six league games. Everything pointed to a comfortable Wigan victory.

But the Addicks showed guts and determination, something that’s maybe been missing in the past three weeks or so, to grind out a hard-earned draw.

Karl Robinson’s men rode their luck at times, however, they could've easily snatched the win.

Their game plan was to sit back and frustrate Wigan… and it worked.

Karlan Ahearne-Grant is maturing

To everyone’s surprise, Ahearne-Grant played as the lone striker in a 4-5-1 formation with Josh Magennis out wide.

And the young attacker, who has featured as a winger and no10 this season, led the line superbly. He offered the Addicks much-needed pace on the break which troubled Wigan’s centre-halves.

His work-rate deserved a goal and he was so close to getting one when he carried the ball 50 yards, only to shoot agonisingly wide.

Ahearne-Grant’s performance showed he’s maturing and improving as a player.

The Wigan stalemate could be a turning point

Robinson said he was proud of the 0-0 draw - and who wouldn't be against the league leaders?

Charlton were expected to lose this game, but did so well to fight for a point.

The Addicks’ next three league games are against Gillingham, Oldham and Bury, three clubs that are struggling.

Nine points should be the target - and that tally is very achievable.

Joe Dodoo was a pointless signing

Dodoo is returning to his parent club Rangers after a hugely underwhelming loan spell at the Valley.

The striker was an unused substitute in nearly every game he was available for, with his last league appearance coming in September. 

And yesterday was no different, he sat on the bench, warmed up at half-time and sat back on the bench. Unfortunately, those will be the highlights of his time in SE7.

The next striker Charlton sign, permanently or on loan, must be good enough to compete with Josh Magennis and Leon Best.

Harry Lennon led by example

Lennon started his first league game in 14 months and it seemed like he’d never been away.

The injury-plagued defender was Charlton’s best player on the night and managed to keep Wigan’s in-form striker Will Grigg quiet.

However, another injury forced him off in the second-half to end his eye-catching display. He’ll miss the Gillingham game, but hopefully it’s not too serious.

He had the most Football League experience in Charlton’s back-four and played with so much confidence.
