The 22-year-old made a prominent rise, with former managers Pep Guardiola and Tito Vilanova both giving him regular exposure.
However, Tello has made just 16 appearances in all competitions this term under the guidance of Gerardo Martino.
With the January transfer market in full swing, Tello has been linked to numerous clubs, including Liverpool in the Premier League, but the winger claims he has plenty more to offer Barcelona.
Despite starting in Barcelona's 2-0 cup victory against Getafe on Thursday, Tello has completed 90 minutes just twice in La Liga but maintains he is happy at the Nou Camp.
"The most important thing is to play, get time on the pitch and work hard," he told the Catalan club's official website.
"You always have to give the best of yourself and take advantage of your opportunities. I'm happy here.
"I'm not playing as much as I did last year, but I'm not giving up."
Although admitting he feels more at home on the wings, Tello understands game time is the most important thing for his development.
"I feel good playing on the right," he added. "The important thing is to get minutes.
"After that, with Neymar's injury, I went to the left side - I feel good on either side of the pitch."
Barcelona travel to face Levante in La Liga on Sunday in a game you can see live on Sky Sports 2 from 6pm.
