Sheffield Wednesday beat Bristol City 2-0 at Hillsborough this weekend.
Wednesday beat Bristol City 2-0 yesterday, with Bannan playing a starring role.
The Scottish midfielder scored the Owls’ opener and generally dictated the play of the match.
And even Johnson admitted that his side could not cope with Bannan at the weekend.
“We weren’t bright enough, we weren’t sharp enough and we couldn’t stop Bannan dictating things,” Johnson said.
Wednesday’s victory over Bristol City has given them an outside chance of making the play offs again.
The Owls’ hopes had looked over after defeat to Aston Villa, but it still remains a possibility now.
Wednesday are currently four points behind Derby County, with two games remaining this term.
Steve Bruce’s side’s remaining matches come against Preston North End and Queens Park Rangers.
