Shakhtar Donetsk clinched its fourth successive Ukrainian Premier League title on Sunday but coach Mircea Lucescu was not impressed by his players' performance in their 1-1 draw with Metalist at the Donbass Arena.
The hosts looked set to succumb to Marko Devic's goal just before the break, but they snatched a championship-winning point through Ilsinho with just six minutes to go.
Lucescu was delighted that Shakhtar had sealed the title but he felt that it had been guilty of complacency during the first half.
The Romanian told his club's official website: "We knew the players’ thoughts: 'We'll win the league title anyway, if not today, then in the next game.' And so on.
"I asked the lads to properly approach today's match, respecting themselves and the opponents but in the first half, we played below our capabilities.
"Since we became the champions today, I want to congratulate all the players. And to wish them to respect this title before the end of the league season - in all the remaining matches."
Shakhtar's draw with Metalist moved it 15 points clear of its opponent, which is tied for second with Dynamo Kiev, with just four games to play.
