The Blues attacker snubbed the chance to team up with Belgium’s under-21 squad.
Musonda told the Belgian FA he didn’t fancy being involved with the U21’s Euro 2019 qualifying clash with Turkey.
The game eventually finished 0-0.
Speaking to Belgian news outlet DH, former Everton boss Martinez appeared to criticise Musonda’s decision although didn’t mention him directly.
He said: “Johan (Walem) has one of the most complicated jobs in football: to manage to involve U21s who are very talented and who, sometimes, feel that going there is not rewarding. That’s the truth.
“They are players that are important in their club, and whose next goal is to be part of the national team.
“It’s our role, and I include myself here, to let them know how important it is for these young players to go with the U21s and win games.”
Eden Hazard – who is yet to kick a ball this season after breaking his ankle in June – flew home to prepare for the senior team’s upcoming World Cup qualifiers
The midfield maestro was similarity critical of Musonda’s snub.
He said: “I don’t know the reason for him not coming to the U21s.
“However, he should have come, even if he didn’t want to.
”In my five years there, no young player has come through at Chelsea.”
Musonda has managed just one first-team appearance for Chelsea since being snapped up from Anderlecht’s youth ranks.

Frank Lampard back at Chelsea coaching the U18s on Wednesday
As shown briefly on Chelsea TV’s latest training ground report, Frank Lampard was back at Cobham on Wednesday, helping out his good friend and former teammate Jody Morris in coaching the U18 side ahead of their game against Arsenal on Saturday.

Of course, it was more than just a friendly social occasion; Lampard is working towards his coaching badges and they require some actual hands-on work at a training ground, not just book and classroom learning. It’s unclear if this was a one-day event or a slightly longer assignment, but it’s probably the first of several to come in the future (and perhaps eventually at a higher/older level, too).
Chelsea are always more than happy to help former players in such regard — many of whom then go on to leverage that experience into actual jobs at the club or elsewhere — and we were undoubtedly delighted to extend this sort of help for Super Frank as well.
Lampard has been keeping busy with a bit of punditry this season for BT Sport, but it’s nice to see him not forget his future coaching plans and continue working towards them (just as JT and Ashley Cole have been doing as well, or at least considering in Ash’s case).
Good luck, Frankie!
