Sheffield Wednesday striker Clinton Morrison has told BBC Radio Sheffield the players must take some blame for the recent dip in form.The Owls have dropped to tenth in League One after a winless start to 2011 and there have been calls for manager Alan Irvine to go. [LNB]But Morrison believes the time is not right for a change of management. [LNB]"We need to stick together, I do not think the right thing to do now is to say 'Let's sack the manager', he said. [LNB]"We are still in the January transfer window and I think Irvine is going to try and bring in a few more players, so we have to back him." [LNB]But the experienced striker, who has also played for Crystal Palace, Birmingham and Coventry City, said the players understood the fans' frustrations. [LNB]"They pay their hard-earned money to see us and we are just not producing at the moment, it is not a nice place to be," he acknowledged. [LNB]"But if we do not learn from our mistakes then we are never going to get out of this league," Morrison added.
