Former Phoenix striker David Williams will reunite with former teammate Roy Krishna in India after signing a two-year deal with ATK in the Indian Super League.

The Kolkata-based club confirmed the signing of Williams on Friday, 10 days after announcing Krishna would be taking his prodigious talents to India.

Williams was tipped to follow coach Mark Rudan to A-League expansion side, Western United, but will instead re-form a deadly attacking combo with Krishna in India.

The duo will provide a much-needed goal-scoring spark for ATK, who ended last season in sixth and scored just 18 times across 18 games.
