Erik ten Hag said it would be "normal" if he has already held talks about becoming Manchester United's next manager.
The Ajax boss did not confirm whether discussions have taken place, and stressed he would wait until the end of the season before declaring his intentions.
But the 52-year-old appeared to give a strong hint his future could lie at Old Trafford, and said he hoped Ajax would understand if he elects to leave a year ahead of his contract expiring.
In an interview with Germany's Sport1, Ten Hag was asked about reports he has already spoken to United about the vacancy that will materialise when interim manager Ralf Rangnick steps aside.
"Everyone knows each other in the industry. There are always talks with representatives from other clubs, that's normal," Ten Hag said.
"Manchester United is a great club with great fans. But I can only repeat myself: My full focus is completely on Ajax. We are already planning for the new season."
Ten Hag has stuck by the line that his immediate attention must be on the present, with Ajax in a battle with PSV for Dutch league and cup glory.
"But in football you never know," he said. "I don't want to rule anything out."
He said outside interest would be "a distraction", adding: "If at some point I should decide to take the next step, I hope that people here will understand."
Ajax will hope to retain the coach who joined in December 2017 and helped the team reach the 2019 Champions League semi-finals, landing the Eredivisie league title in the same year and also in the 2020-21 campaign.
"I've sat down with Ajax after every season so far," Ten Hag said. "That will also be the case this time. I can say that Ajax and Erik ten Hag are very happy with each other at the moment."
Paris Saint-Germain head coach Mauricio Pochettino is reported to be the other main contender for the United job, with the incoming boss set to take charge of a team that last won silverware in the 2016-17 season, when they landed the EFL Cup and Europa League titles.
United sit sixth in the Premier League heading into the weekend, four points behind fourth-placed Arsenal who have played one fewer game, and a major squad overhaul likely awaits the next manager.
Ten Hag's Ajax are top by two points from PSV in the Eredivisie, and the title rivals also meet in the final of the KNVB-Beker on April 17.
