The former Town captain saw the team record a seventh win in ten Championship matches to move back into the play-off places, courtesy of Elijah Adebayo’s 38th minute goal.
Afterwards, he said: “You can’t play unbelievable football every week and tonight was a night for the basics. The pitch was a bit bobbly out there and hard to gain momentum at times, but I think it was important that we did the basics well and we did that.
“We stayed in the game, defended our box really well when we had to and we probably had the better chances over the 90 minutes. Another clean sheet was important, so it’s definitely a night to look at the positives.
“The way the lads defend for each other, the way they work hard for each other is just so impressive. That togetherness is worth an extra few points at the end of the season. When we go a goal ahead we rarely get beaten, so to get that first goal and see it out was excellent.”
Emergency loan keeper Alex Palmer made two big saves, one in each half, and provided the assist for Adebayo’s goal.
Asked about the West Brom man’s performance, Sheehan said: “I thought he was fantastic, coming for crosses and really covering his box well. His kicking was really good and sometimes coming into a club – I think he came in on Friday before the Saturday game in a real difficult venue against Middlesbrough – I thought he was outstanding again tonight.
“He did whatever he had to do, along with the back three in front of him, Belly and Breezy and the midfielders. Everybody worked hard, everybody gave it everything, we did the basics really well and we proved that we are really stubborn to beat."
Sheehan, who returned to Kenilworth Road in a coaching role in January, has seen the Hatters rise from the bottom half of the table to sixth by winning nine of 13 league games in that time.
“Without getting carried away, we know there is a lot of football to be played but we are in an excellent place, the club is in an excellent place, it is a wonderful place to work, you’ve got wonderful players and staff, everyone is pulling together, we've got wonderful fans," said the 35-year-old.
“I think I’m repeating myself possibly from a few years ago, but when everyone is pulling in the right direction, something good comes from it, and the togetherness here at this football club is outstanding, it really is.”
On the 1,757 Hatters in the away end, the Irishman added: “They always make a lot of noise, they are outstanding. After a long trip on Saturday to Middlesbrough, to recover, with the games are coming thick and fast, and to have them getting behind us and getting us over the line, I thought they were outstanding again tonight.”
