Subquery as a column : Nested Subquery

I have two tables 'Student' and 'Team'. i want to display count of student according to Team Name, Team_id from team is primary key.

i tried like this 

(SELECT(SELECT team,count(*) as team 
            FROM student GROUP BY team) AS total,
     (SELECT team_name 
          from team WHERE team_id IN (SELECT team 
              FROM student GROUP BY team)) as team)

i want output as

Team Name      Total Student
-----------------------------
Team 1           25
Team 2           10

Table ' Student'

CREATE TABLE IF NOT EXISTS `student` (
  `id` int(255) NOT NULL AUTO_INCREMENT,
  `rid` varchar(200) NOT NULL,
  `sid` varchar(200) NOT NULL,

Seems you are looking for this

 select a.team_name, count(*) 
 from  team as a
 inner join student as b on a.id = b.team
 group by a.team_name

(use your proper column for join)
