# Moving the labels under the unit circle

The labels -1 and 1 in the following (TikZ)-code are under the line of the unit circle:

\draw (-1.5,0) -- (1.5,0);
\draw (1,0) arc(0:360:1);
\foreach \i [count=\j] in {-1,1}
{\draw (\i,0) coordinate (x\j) edge ++(0,2pt) -- ++(0,-2pt) node [below=5pt, anchor=mid, font=\scriptsize] {\i};}


How can I correct that? Thank you!

A little simplified:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw[font=\scriptsize]
(-1.5, 0) -- (1.5, 0)
(-1, 0) node[below left] {$-1$}
(1, 0) node[below right] {$1$}
