We go to the Reebok on what could be a key night in the race for the top four in the Premier League with Newcastle, currently fifth and level on points with us, travelling to sixth-placed Chelsea, who are a point adrift.
Bolton have lost just three of their last nine league matches but remain in the bottom three.
“We’ve been to Bolton enough times over the years and it’s always a difficult place to go,” said Harry.
“They are playing well and Owen (Coyle, manager) has got them going at the moment.
“It will be a hard game but we’ve got to go there and be positive.”
Victory at Bolton would take us just one point behind Arsenal in third with two games remaining.
“You never know,” added Harry. “You just have to keep going. That’s all we can do.
“We’ve two tough away games this week and then a tough home game against Fulham to finish with. So that’s three hard games.
“Newcastle have three tough games, for sure. Chelsea might just have the best fixtures. We have to keep going and if we play well, we can do it.”
In terms of team news, Harry was keeping his cards close to his chest. “We’ve one or two little niggles, but we’re not too bad really,” he said.
