Stuart McCall was pleased to clinch a Scottish Premier League top six place ahead of Motherwell's Scottish Cup semi-final against St Johnstone.
The 0-0 draw with Hearts ensured 'Well will feature in the top half of the table when the league splits.
"All in all I'm so proud of them and delighted with them," said Motherwell boss McCall.
"I've got a really difficult job next week, not only to name the 11 but to name the 16 (against St Johnstone)."
McCall left several of his first-team regulars on the bench at Tynecastle and handed a debut to 17-year-old Stewart Carswell.
"I thought he was fantastic," said McCall. "He very rarely gave the ball away and worked ever so hard up against a very good player in Ruben Palazuelos.
"I think he's got to be very proud and his parents were here today and I'm pleased for them because he had a great debut.
"Steve Jennings was suspended, Francis Jeffers and Gavin Gunning injured, Steven Hammell was on the bench and we left Keith Lasley, Jamie Murphy and John Sutton out because they've got little knocks.
"It was a good game for a 0-0. Hearts had a lot of the ball but we had some great chances, we hit the post, hit the bar, Sutton had a chance at the end."
Chris Humphrey was replaced during the match and though McCall expects the winger to recover in time for the semi-final, he has another injury concern.
"Thankfully it's only a dead leg so he (Humphrey) will be fine," added McCall.
"The one possible casualty for next week will be Steven Saunders, who has nicked his hamstring.
"The rest of them that have been out and been rested will all be fighting fit."
