Let $S^n$ be the sphere of dimension $n$. In order to construct a map $f:S^n\rightarrow S^n$ of degree $d\geq 2$ one has the following construction: Let $K$ be the complement of $d$ 
disjoint n-dimensional open discs in $S^n$. Then collapsing $K$ to a point we find that 
$S^n/K\simeq \bigvee _{i=1}^d S^n$. Identifying (choosing a homemomorphism) each of  the sphere in the disjoint union  with $S^n$ (with the approriate orientation), the composition of the two  maps
$$
S^n\rightarrow  \bigvee _{i=1}^d S^n \rightarrow S^n,
$$
gives us a map  $\phi_d:S^{n}\rightarrow S^n$ of degree $d$. 

In general, if $f:S^n\rightarrow S^n$ is a map of degree $d$ and $x\in S^{n}$ is such that the fiber $f^{-1}(x)$ is **finite**, then one has from excision theorem that 
$$
\sum_{y\in f^{-1}(x)} deg_f(y)=d.
$$


Q1: How would you construct a (continuous) map $f:S^n\rightarrow S^n$ of degree $d$ with a point $x\in S^{n}$ such that the fiber $f^{-1}(x)$ is infinite?

Q2: When the fiber $f^{-1}(x)$ is infinite, is it possible to take some kind **natural** average sum over the local degrees of the elements of $f^{-1}(x)$ in such a way that the sum converges to $d$ (you may assume that $S^n$ is endowed with a metric if you think  it helps) ?
