The IFK Gothenburg talent is trialling with the club this week.
The 19-year-old has joined the club for two days of training this week as he bids to earn a permanent move away from Swedish football.
When discussing his temporary switch to England The Stoke Sentinel quote the player as saying:
"I see it as an opportunity to see how it works in an English big club.
"Further than that, I have not thought about it.
"It's exciting to test their environment."
The same paper reports that he was due to spend time with Stoke over Christmas but scheduling conflicts ended such a move.
Whether or not this is the means toward a permanent Stoke transfer remains to be seen - with the Swedish league starting up again next month.
However it is likely that Stoke are simply making their interest known and seeing what he is capable of, rather than pushing for a deal at this moment in time.
Engvall scored five goals in 25 appearances for current club IFK Gotenburg last season and has also featured for the Swedish senior side twice this year.
