The 17-year-old is being monitored by the Premier League side.
The 17-year-old only made his debut for the first-team in May, and made one more appearance before the end of the season, scoring in the 4-2 victory against Kilmarnock on the final day of the campaign.
And despite the Arabs' relegation to the Scottish Championship, his emergence into the side has helped create some optimism ahead of the new term.
However, that optimism could be taken away if the Potters manage to land the starlet. The Scottish Sun reports that the Premier League side could test United's resolve to keep hold of the youngster by making an initial £250,000 bid.
While a move to the Britannia Stadium may seem to be something of a no-brainer, Souttar may feel that staying where he is may actually be the better move for his career for the time-being.
At Tannadice, the youngster arguably stands a much greater chance of enjoying first-team football than he does in England.
However, moving to the Premier League and coming up against better players would undoubtedly be the kind of move that Souttar will have to make at some stage if he wishes to reach his potential, which may tempt him to move on should a bid come in.
