Daniel Pudil is confident victory over Ipswich Town and Cardiff City at Hillsborough will secure Sheffield Wednesday a top six spot in the Championship.
Wednesday have a five point lead over seventh placed Cardiff and are a further three points ahead of Ipswich, who visit S6 on Saturday.
Pudil said victory in each of those two home games is vital and is confident that will be enough to fend off the challenge of the chasing pack.
“We know we have still got Ipswich and Cardiff to play at home,” the left back said. “Those games will be really important to win.
“If we win both of them, we will be 100 per cent in the play-offs.”
As they prepare to welcome Mick McCarthy’s side on Saturday, Wednesday are looking to bounce back from last weekend’s horror show at struggling Bristol City.
Czech Republic international Pudil insists Wednesday’s players always have each others’ backs and has backed them to stick together.
He said: “We have a good, strong squad and everyone is working hard for each other.
“We are playing together. Even if someone makes a mistake, we know someone else will help them out.
“We have backed each other up.”
Both Cardiff and Ipswich failed to take advantage of the slip as they were beaten by Fulham and Brentford respectively.
