Chris Blom’s invincibles are treating Saturday’s London 2 North game at Chelmsford as a pivotal moment in their promotion quest.

With six wins from six, and maximum points, Ipswich are perched proudly at the top of the tree ahead of a trip to Essex where Chelmsford will attempt to clip their wings.

The derby will be only Ipswich’s second against a current top-six team and the visit to Coronation Park could be their toughest yet, according to South African talisman Blom.

“Games against Chelmsford are always big, but Saturday’s game has grown because they are in the top four and chasing top spot,” said Blom, whose side are currently nine points clear of Eddie Gooby’s team.

“That way things are going, we will head into the game confident, being top of the league, but with a nervous confidence.

“We are treating every game like a promotion game but we are not arrogant and have to be humble. We must do everything we can during the week to strengthen our game.”

Ipswich have won two of their last three games away at Chelmsford and go into this game on the back of a 59-17 home win against Basildon last weekend. The week before they enjoyed a morale-boosting 47-28 success at Enfield – their first success against the Ignatians for two years.

Coached by Johnny Breedt, pictured, the Suffolk team head south as the form side, although Chelmsford are unbeaten in four, so something will have to give.

“Chelmsford know their pitch and play the slope there very well, while their support base is immense,” added Blom.

“It’s always a close game and they know where to play in the corners but we have won there twice out of the last three seasons.

“The slope can play a big part there but it all depends on the day how you use it. I like to play up the slope first, but I will keep the opposition guessing for as long as possible.”
