Too young to tell at the moment, might need to wait to next year or even the year after for its typical leaf shape to develop. Leaves on maple seedlings are often very different to adult leaves of the same species. What maples old enough to produce seeds are growing nearby?
Pretty sure that's a young pseudoplatanus, Alex. Very pretty. May end up being a variegated one. Be careful getting it out of the ground! -E
