While those of the Magpies' side that have been away on international duty recently will be given extra time before their return to the club, the majority of the team - including the likes of Florian Thauvin and Fabricio Coloccini - are scheduled to come back this week, the Chronicle reports.
The Chronicle adds that both Thauvin and Coloccini have been linked with seeking to leave St James' Park this summer, with the former reportedly less than keen on the idea of plying his trade in the second tier.
Regardless of their reported desire to move on however - and Newcastle's willingness to sell the pair if a suitable bid comes in (via Chronicle) - Benitez wants all of his squad to report back to the club on time, and is prepared to punish any players who fail to do so.

The Chronicle suggests that those players could be disciplined and fined, and may be instructed to train with the reserves, rather than the first-team.
If any of the members of the squad were to return later than expected, it could suggest complacency on their part over the league they will be playing in next term if they stick around.
Benitez may well be aware that while the Magpies will undoubtedly be one of the favourites to go up, promotion is not a guarantee in the slightest and despite having players of Premier League quality, the Championship asks different questions that the side may sometimes struggle to answer.
But if he can instil the right attitude into the squad, he will surely find it much easier to lead the team back to the top flight at the first time of asking, and subsequently, re-establish them as a force at the highest level.
