David Castaneda struck at the half-hour mark before adding another two in the second half to net the first hat-trick of this season's I-League. The Colombian striker has now amassed nine goals already in just eight matches.
The hosts have had a poor start to the new campaign, suffering six straight losses and registering zero points to their name. With one-third of the league's fixtures already complete, time is of the essence for Sudeva as they sit six points behind their closest rivals on the points table.
Two second-half goals by Abdoulaye Sane and Lamgoulen Hangshing helped Churchill win two matches in a row to take their points tally to eight from seven outings. Sudeva Delhi FC, on the other hand, are yet to pick up their first point after playing six matches.
Aizawl earned just a single point in their last two games. They salvaged a draw against Churchill Brothers after Henry Kisekka scored the equaliser in the final quarter of the game.
Dodi Ndo's second-half strike, followed by a Shijin T brace gave the defending champions their first win in four matches, taking them to third place on the standings. However, for the visitors, the result means a fifth straight loss as they remain rooted to the bottom of the points table
The defending champions return back to their home turf after facing a series of disappointing results since their back-to-back wins at the start of the season.
Striker Jourdain Fletcher's thumping strike early in the second half won all three points for the Orange Brigade, who had as many as 11 shots on target in the entire match.
This will be Aizawl's third successive home game. They have a solitary point in two matches so far, with a 1-1 draw against TRAU, followed by a narrow 0-1 loss to champions Gokulam Kerala on Friday.
Jourdain Fletcher's long-range shot proved to be the difference between the two teams as the hosts got their first win of the new campaign, while Sudeva suffered their second loss on the trot.
