Sheffield Wednesday have won their last four fixtures in all competitions.
The Owls have made an impressive start to the 2015/16 campaign, and they have won their last four fixtures in all competitions.
Carlos Carvalhal's side's good run of form has seen them accelerate up the Championship table, but Bannan has called on the team to be more ruthless.
“We could have been more comfortable in the games and we probably should have been," the midfielder said. "I know we’ve missed chances to put the game out of sight but that happens.
“We’ve won those games, we’ve come through them and we’ve kept going on this really good run that we’re currently on."
Wednesday struggled to find a prolific number nine last season, and it appears as though they may endure similar struggles this time around.
Despite a lot of money being invested in the squad, their striking ranks are still an area which could be improved.
Wednesday have been linked, by the Shields Gazette, with a loan move for Sunderland striker Danny Graham, but it is unclear whether Sam Allardyce will choose to bring him back in from the cold.
As a result, Carvalhal will have to keep persevering with the options that he already has in his squad, and will hope to see the likes of Lucas Joao and Atdhe Nuhiu on the scoresheet more often in the future.
