Motivation levels
Interestingly, both coaches have used 19 and 20 players this season in the hopes of reviving their campaigns.
However, that too hasn't improved their results. Gregory went on to rue the fact that their title defence has fallen flat, so early into the season, and questioned the motivation levels of this team.
Opportunity missed
"I'm really amazed to see that no one in the ISL has had the ability to come back and retain the title. I didn't envisage the season to pan out this way. But maybe there hasn't been the same hunger in teams trying to retain the title.
"It appears we won't make it to the play-offs this season. And that is definitely a huge opportunity missed this season."
What is perplexing is the manner in which they haven't really got going at either end of the field. The defending champions have scored a mere eight goals despite seeing a lot of the ball.
All eyes will be on Jeje Lalpekhlua who needs to rediscover his scoring touch ahead of the AFC Asian Cup next month.
Attractive brand
On the other hand, Delhi Dynamos have flattered only to deceive. Despite playing an attractive brand of football, the Lions have not been able to see out games.
In three of their last matches, they have taken the lead only to concede goals later in the game and lose out on three points.
"We are playing good football. We are creating a lot of chances and not scoring so much. That is a problem. We also have to improve our defence as we are conceding goals," said Delhi coach Josep Gombau.
Frustrating run
"Even when we are playing away we are creating chances but not getting the results which are frustrating. We will go with a winning mentality to win the last game of the year."
Gombau will miss the services of Adria Carmona, who is injured and Narayan Das, who has amassed four yellow cards.
What would also concern the Spanish coach is that none of his three wingers, Lallianzuala Chhangte, Romeo Fernandes and Nandakumar Sekar, have a single assist to their name.
Can Chennaiyin pick their first home win or will it be Delhi finally putting an end to their frustrating winless run?
