Tommy Wright claims his St Johnstone side gave a 'workmanlike performance' in beating FC Minsk 1-0 in the first leg of their Europa League third qualifying round tie.
Steven MacLean netted the only goal in Belarus after 68 minutes, to put Saints in control ahead of the second leg at McDiarmid Park.
Manager Wright said: "I don't think we reached the highs that we did in beating Rosenborg in terms of performance. We were workmanlike.
"It was quite warm out there and very sticky and a few of our players looked a bit heavy-legged.
"But they only really caused us problems on the counter-attack. They were not breaking us down.
"It wasn't pretty, because they are not a pretty side to play against but we got the result we deserved.
"We knew they were not technically better than Rosenborg but had pace up front.
"However, it is only half-time and we will not take anything for granted."
As for MacLean's second half goal, Wright added: "It was a classic striker's strike.
"Steven has taken it well and hit it across the keeper. You know what you get with Steven. He probably doesn't get as many goals as he should because of all the work that he does outside the box for the team."
