Steven Naismith has warned his Rangers team-mates they will need to improve to secure the Treble this season.
Naismith was speaking after he helped the Gers claim the Scottish League Cup on Sunday, courtesy of a 1-0 win over St Mirren at Hampden Park.
But Naismith says that better is needed if they want to add the SPL and Scottish Cup to their tally.
"We always strive for success at Rangers, but if we continue playing like we did against St Mirren then I don't think we will be winning the Treble," he said.
"In the next month, we have a lot of big games coming up in both the league and cup, and we will need to put in some good performances. We will need to play better than we did against St Mirren to win them.
"It was looking as if it wasn't going to be our day at Hampden. In the first half we didn't play well, in the second half we had two men sent off and it was looking ominous.
"In the end, we managed to sneak a goal. Big Davie Weir played it wide to me, the park opened up for me, I put the ball into the area and Kenny did well with a great header.
"Kenny put it in the one place the keeper couldn't get it. He wasn't happy with his first-half performance, but went out and showed what a battler he is.
"We will take every game as it comes, but St Mirren showed how tough teams will make it for us as Dundee United did last weekend coming back from two goals down."
