The Frenchman has lit up St. James’ Park with his dazzling footwork and bright attacking play, and the last thing that the Toon Army will want to consider right now is his potential exit.
But perhaps supporters can take some reassurance from John Barnes, who insists that the wide man is at the right club for his career.
"He’s been fantastic for Newcastle,” Barnes told BettingOdds.com. “He’s been incredible for Newcastle. His return from injury really helped them at the back end of the season, and got them out of a bad situation.
“I’m pleased for the fans, and I’m pleased for Steve Bruce, because under difficult circumstances when the harmony wasn’t right because of the relationship the fans have with the owner, I think they did well to stay up.
"There was a lot of negativity surrounding the whole situation, and they did well to come out of that, and Saint-Maximin had a big part to play in that.
“He has to choose his club, and Newcastle is the right club for him, because they give him the ball and say ‘do what you want’, and he won’t be able to do that at a big club, he will have to play in a system.
“He can do what he wants, dribble when he wants – and they won’t criticise him. He won’t be able to do that at a bigger club, so I can’t see him going to one of the ‘big six’.”
