Albie Morgan must work on his fitness levels if he is to continue improving.

That is Lee Bowyer’s main message to the 19-year-old following his impressive performance against Rochdale, in which Charlton eased to a relatively comfortable 4-0 win.

Morgan’s raking pass to split open the opposition defence set up Lyle Taylor for a one-on-one chance that the Addicks’ leading scorer finished with aplomb.

And with a little more luck he could’ve got on the scoresheet himself, with Dale goalkeeper Josh Lillis pushing away his rasping volley in the box.

The midfielder, who has enjoyed first-team opportunities since making his debut earlier this season, is rated highly by Bowyer and Charlton’s coaching staff.

But Bowyer wants to see the teenager become fitter if he is to continue to get more time in the starting 11.

“He's been very good,” the Addicks boss said. “He has ability, I think that's obvious to see. His awareness and his cleverness ... again, he has to work on his fitness.

“But his volley that he had and, technically, he's very, very good. He's a gifted player. But he has to work on his fitness side of it.

“[He could have scored] two or three, so yeah. He'll score, it'll come for him.

“He's a young lad and he just has to keep working hard.”

Charlton will take on Doncaster Rovers in the League One playoff semi-finals, with the first leg being at the Keepmoat Stadium on May 12.

Then, because the Addicks finished third in the table, the second leg will be hosted at The Valley on May 17.

Unfortunately for Charlton stalwart Chris Solly, he’ll be missing the first leg as he serves the last of his four-match suspension.

But the mainstay defender is expected to be back for the second leg, something Bowyer will undoubtedly see as a boost.

“Solly's experienced,” he added. “He's a great pro, great player to have around the player, he's got loads of experience to help the younger lads - because we have got some young players playing - so yeah.

“It’d be good to get him back for the second leg for sure.”
