His early performances for Andorra at youth level led to him being offered a trial with La Liga side Valencia after being spotted by one of the club's scouts.

[6] In 2008, Sonejee was approached over a potential move to his parents' homeland India, receiving offers from East Bengal and Churchill Brothers.

He originally signed a deal with East Bengal but later decided to accept the offer from Goa-based Churchill Brothers as he believed the culture in the city was more European based and would be easier to acclimatise to and the club was closer to the home of his wife's parents.

When Churchill attempted to register Sonejee, the All India Football Federation (AIFF) blocked the move as they had already received a registration request by East Bengal.

[8] The situation eventually led to Sonejee backing out of a move to India, having spent a month training with Churchill,[5] and instead signing for Santa Coloma in his home nation.

[4] The most successful period of his career came during a four-year spell with FC Santa Coloma between 2008 and 2012 where he helped the side to win back-to-back Primera Divisió titles during the 2009–10 and 2010–11 seasons.

[1] After returning to his first team Sant Julià in 2015, Sonejee undertook his coaching badges alongside his playing career, obtaining a UEFA A and B Licence.

He captained the team for the first time on 12 October 2005 against Armenia, scoring an own goal in a 0–3 home defeat in 2006 FIFA World Cup qualification.

[3] Despite making his debut, Sonejee was still eligible to represent his parents' country India as he did not possess an Andorran passport at the time.

He later admitted that, had he received a call up, he would have switched allegiance to India but stated "since I saw nobody was interested, I decided to continue playing for Andorra, and obtained that passport.

[5] Sonejee retired from international football on 12 November 2015, with his final game for Andorra coming in a 1–0 friendly home defeat to Saint Kitts and Nevis; his national record of 106 caps was surpassed by Ildefons Lima in August 2017.
