Paul Dickov read the riot act after labelling his side’s display in last night’s 4-0 defeat at Middlesbrough as “unacceptable”.
Slipshod Rovers were second best all night as Boro ended a difficult week - which saw Tony Mowbray sacked on Monday - on a real high.
Goals either side of half-time from Albert Adomah (2), Kei Kamara and debutant Daniel Ayala ensured Boro claimed their 10th win in 13 league meetings with Rovers.
But Dickov was furious with how easy his men made it for the Teessiders - and lambasted his players at full time.
“It was poor, really poor,” Dickov, who yesterday allowed winger Kyle Bennett to join Crawley Town on a month’s loan, told The Star. “For the first time since I came in here it’s difficult to pick any positives out of it.
“We pride ourselves, not just on passing the ball but our work rate and desire without the ball. That was missing tonight.
“I’ll find out what went wrong and put it right because I’m not accepting that.
“We played against a team who had more energy than us and more desire than us, and the result reflected that.
“To be fair to the boys they’ve been great up to this point but they’ll soon realise I won’t accept a performance like that.
“I’ll take getting beat. But getting beat in that manner is unacceptable. If we don’t try and do the right things, with and without the ball, we’ll not win football matches.”
Paul Quinn was withdrawn at half-time after suffering a dead leg, forcing Dickov into putting on Yun Suk-Young, who was signed just hours before kick-off on loan from Queens Park Rangers. The South Korean international has been brought in as cover at left-back for the injured James Husband. He will initially stay with Rovers until December 31.
Suk-Young left South Korean side Chunnam Dragons to join QPR in January 2013.
