Newcastle United have been to Spain to partake in some warm weather training.
Newcastle have travelled to La Manga in Spain this week, after they were beaten 5-1 by Chelsea in their most recent match.
And Merson feels that Newcastle are sending out entirely the wrong message to the squad and the supporters by going abroad after such a poor result.
“There’s a time for it,” the former Arsenal midfielder said. “You have to draw a line, and say that we cannot afford to go away.
“Newcastle is a working class place, where people spend all their money on going to watch the club play.
“[Going to Spain] was the worst move that the club could ever make.”
Newcastle’s training camp in Spain has been designed to help their four new additions settle into the squad.
The Magpies spent more money in January than any other English side, but their new recruits have not been able to guide them away from trouble.
Newcastle are currently in the relegation zone, and they will be looking to use the time away from competitive action to iron out the faults in their game.
McClaren’s side have conceded far too often this campaign to be successful, and they have also struggled going forward - which isn't a combination that is likely to create success.
Newcastle return to action on March 2nd, with a match at the Britannia Stadium against Stoke City, where they will be looking to end their terrible run of away form.
