Partick Thistle manager Mark Wilson tells BBC Scotland: "It's really raw. What we put in tonight, both legs, the full season, and it ends just like that.

"There's been a real connection with the fanbase, you see the ovation they get at the end. I couldn't be prouder. I think it's the best group I've ever been involved in.

"I was pretty relaxed coming into the game. We just weren't clinical enough. We dealt with [set-pieces] so well apart from [the winning goal].

"That's the fine margins that can cost you. Football's cruel. We have to go again."

St Mirren defender Alex Gogic tells BBC Scotland: "To go down, it would be a big change for the club, for people the fans don't see every day.

"For any club, it's a big change to be in the Championship and you see it's not easy to get back up. We had to make sure we stayed up."

On the prospect of Craig McLeish being offered the permanent role, Gogic says: "Yeah, of course, whatever the club chooses. If he has a pre season, it will probably be better than what it is. If the club decide to go his way, we'll all be behind that."

St Mirren fans...

Craig McLeish for the permanent role: yes or no?

Get on those thumbs...

St Mirren caretaker manager Craig McLeish discusses his future with BBC Scotland: "I imagine [chief executive] Keith [Lasley] will start to have conversations about that over the next few days.

"We spoke about taking care of everything and whatever the outcome is, the club will plan their future from there.

"I'm privileged that the club put trust in me to take the team on. I wouldn't be standing here if it wasn't for Stephen Robinson giving me opportunities up to that point, so I have to thank him.

"If I get the opportunity to lead the group, my biggest thing is to make sure we're never in that type of position again.

"I've felt I'm capable of doing the job and handling the full thing. I've felt that from day one. This is what I've always been building towards.

"I can't control when I would get the opportunity. I just had to show I was ready to go and I hope I have shown people that."

McLeish says there won't be much celebrating, and he'll be keen to plan for next season.

When asked by Sky Sports if he wants the manager's job on a permanent basis, St Mirren caretaker boss Craig McLeish replies: "Absolutely. I think everybody knows that by now. Whatever the club decide to do now, that's up to them."

St Mirren interim manager Craig McLeish tells BBC Scotland: "I'm delighted for the players and the fans. The remit when I took over the role was to stay in the league.

"We would have liked to avoid this type of situation, but we managed to [stay up].

"We wanted to make sure the players were remembered as legends at this club after winning the League Cup. We didn't want that black mark against our name.

"First half was nervy, cagey and full of mistakes. It wasn't really tactical, just us controlling our emotions. We did that better in the second half.

"Our bench was a strength. When Partick started to tire we brought on fresh legs, who saw us over the line."

St Mirren defender Marcus Fraser tells Sky Sports: "It's bigger to stay in the league [than score in the League Cup final]. We'll talk about winning the cup more now that we're staying in the league. It was a decent finish, not like me."

St Mirren captain Mark O'Hara: "We were nervous first half, so much at stake. We had everything to lose and they had nothing to lose. It's just relief. To stay in the league and have the cup win, everyone would've taken that."

Aidan Fitzpatrick is now in buckets of tears at the Thistle end.

So much emotion outpouring after such a high-stakes game.

I don't think either team played that well. You couldn't say either team deserved to win. But Marcus Fraser takes that chance so well at the back post.

Tony Watt looks inconsolable as he applauds the Thistle away end. The former St Mirren striker is absolutely devastated.

A real sore one for the Championship side, who were well in this gripping two-legged affair throughout.

So many fans in tears.

That same wee fella is now on the pitch applauding the fans like he's just played the full 90.

Matchwinner Marcus Fraser has just jumped into the crowd and throws his, I'm assuming, wee boy on to his shoulders.

Awk, the wee man looks like he's going to burst into tears.

Wholesome stuff.

It is!

St Mirren cult hero Marcus Fraser secures the Paisley side's top-flight survival.

More play-off heartbreak for Thistle.

It's off the wall from Kyle Turner and surely that's that.

Oh wow.

Gary Mackay-Steven has taken a tumble in the box and wants a penalty.

On second viewing, it's a sensational tackle from Miguel Freckleton!

But Thistle now have a close-range free-kick...

One minute remaining.

This is it.

Alex Gogic and Alex Samuel get involved in some off-the-ball wrestling and it all gets a bit silly.

The pair are booked and St Mirren get the free-kick.

Precious time wasted for Thistle.

Dan Nlundulu, just off the bench, has a goal-bound finish blocked after superb work by Roland Idowu.

Five minutes added.

Thistle build pressure, but the final decision is lacking as St Mirren boot clear. Off goes Killian Phillips and Dan Nlundulu replaces him.
