Lions coach John Mitchell says the Stormers don't have the all-round game to win this year's Super Rugby tournament even though they are still unbeaten.
When the Brumbies beat the Highlanders on Saturday the Stormers were the only team left who are undefeated.
However the draw so far has suited the Stormers as they have only played one match away from home and the one match they did play away was against the Lions who are in the bottom half of the table.
The Stormers held off a second half comeback from the Lions to win 24-19 at the weekend but the result was more of a demonstration of how the Lions are unable to finish rather than the Stormers' effectiveness.
"We knew what to expect from the Stormers," Mitchell told the Times.
"They don't take too many chances and they're predictable. "But they work hard for each other and defend well. They clearly have to improve their attack if they want to win the competition."
Many might see Mitchell's comments as sour grapes from a beaten coach but his words were backed up by Stormers captain Jean de Villiers who was also not happy with the Stormers game.
"We played really well for 20 or 30 minutes and then I think we got a bit complacent," De Villiers said.
"We will take the four points away from home, but when I heard that result at Loftus, and if we play like this next week, the result might be the same for us."
Stormers coach Allister Coetzee preferred to look at the positives ahead of their clash with the Bulls who hammered the Reds 61-8 at the weekend. "Our fitness is unbelievable," Coetzee said.
"If we can still defend as we did at the end when the Lions kept the ball through so many phases and kept us under pressure, then I am very satisfied with the defensive session we had.
"It is a great defensive performance and one thing that a Stormers side will always pride themselves on, and keeping them out those last 10 minutes was something special."
