He represented India at various age group levels, including the Under-20 team that reached the quarterfinals of the 2002 AFC Under-20 Championships.

Pradeep continued to impress at SBT, helping them to win four Kerala League titles.

In 2006, Pradeep made his first big move at club level as he joined National League champions Mahindra United.

He won the IFA Shield and reached the quarter-finals of the AFC Cup with Mahindra and caught the eye of newly appointed India coach Bob Houghton.

Initially he was used as a left back by the English tactician but by the start of the 2007 Nehru Cup, Pradeep was in the India squad as a goal scoring midfielder.

The Indian international did not have a 2011–12 I-League season to remember as he was on the fringes of the first team at Mohun Bagan.

It is also said that head coach Bimal Ghosh and his liking for the city of Mumbai were the two main reasons for him choosing to sign up with the second-tier I-League side.

On 24 November 2013 it was announced that Pradeep has signed for Mumbai on loan from IMG Reliance with three other players Khelemba Singh, Mohammed Rafi and Peter Costa.
