Neil Lennon has cited predictability as the reason for tinkering with Celtic's formation on the weekend.
The Hoops boss resorted to a 4-4-2 diamond rather than his standard formation of 4-2-3-1 at Ross County on Saturday and it paid dividends as the reigning champions came up with a 4-1 victory.
Lennon, who saw Virgil van Dijk and Joe Ledley score doubles, felt he needed to alter things in order to gain a positive response from his players following a 1-1 draw with Dundee United and 1-0 loss to Ajax in the Champions League.
"We changed the shape because I felt we were getting a bit stale. I was worried teams were starting to settle on the way we played," he said.
"That's why we decided to go with a diamond in midfield. We also had extra pace up front by going with Teemu Pukki and James Forrest.
"It worked well. We hadn't worked on this in training but the players are flexible. Guys such as Scott Brown and Ledley can play in different systems. That's what the squad is for.
"I had no qualms about changing it as I felt I had to."
