Fresh off the back of Saturday’s late win against Luton Town, Stevenage face Premier League side Stoke City in the EFL Cup on Tuesday night as Mark Hughes’ men are set to travel to the Lamex Stadium.
Speaking ahead of the game, a level-headed Sarll warned that although the weekend's win was a joyous one, there is still plenty of improvement needed.
“It was obviously nice to get a win and it was nice the way it unfolded at the end. Everyone goes home with that lasting imprint in their mind of Matty Godden scoring.
“I came away very similar but by Sunday after watching the game and analysing it in calm reflection, I think there is so much more we have to do and the reality hit home.”
Sarll knows that Tuesday night will offer a very different test and he says that every single player will have to play to their best in order to get something out of the match.
“It gives the players a chance to play against the people they wait up to watch on a Saturday night on Match of the Day,” Sarll said. “It is a good chance for them and some of the younger ones that will play to benchmark and test themselves against some very good players.
“It will be another one where on the evening if we have two, three under-performing it will be a real, real long night so everyone has to be at their very best tomorrow night.
He added, “We know that whatever group of players come from Stoke tomorrow night, it is going to be good group of players.”
The manager also reiterated that despite going into the game as big underdogs, they will be doing everything they can to come away with a victory.
“It is a good one for us and for our efforts at Ipswich, we deserved it. I have been involved in this competition as a coach where we have seen off Premier League sides and had good runs.
“We are in the game to win it. I said on Saturday, we pay these gentleman to win football matches for the club and we have got to go try and win it tomorrow night.”
Tickets are available online, in-store or from the turnstiles on Tuesday night.
