Charlton boss Lee Bowyer believes there is still a long way to go in the League One promotion race following their 2-0 win at mid-table Plymouth Argyle.
Athletic are fifth, six points behind second-placed Barnsley with a game in hand.
Bowyer said: “I honestly believe we have got a chance of winning all six. Will the team above us make mistakes? I believe they will.”
Charlton goalkeeper Dillon Phillips saved Graham Carey’s 39th-minute penalty and – two minutes later – Charlton striker Lyle Taylor headed his 19th goal of the season, his 16th in the league.
Fellow forward Igor Vetokele got between stopper Matt Macey and central defender Niall Canavan to convert Jonny Williams’ cross and make it 2-0 in the 49th minute.
Delighted Bowyer said: “You have to give Plymouth credit – they are a good side and this time last season they were fourth.
“They’ve got players that can hurt you – (Ruben) Lamerias, Carey and the striker has scored something like 17 goals. I can’t understand how they are down there.
“In the first half an hour of the game they were the better side. They won a lot more second balls, they moved the ball well and they created chances.
“Once Dillon makes the save, it was a wake-up call and we start doing what we are good at. We started dominating the game, from the penalty save onwards, we were the better side.
“Lyle showed great movement for his goal and Jonny was exceptional down the left for our second.
“We had to change things shape wise because they were causing us damage.
“Lameiras was playing up top and then dropping into areas that our centre-halves couldn’t go all the way with him. That was causing us problems, I had to change it and we were comfortable in the end.
“Igor worked hard and deserved a goal.
“The main thing for me is that we keep winning games. The fans were great today.”
Plymouth boss Derek Adams said: “We were very good in the first half I thought we looked like the team in the play-off position.
“For 45 minutes we were excellent, matched them up, played a diamond formation and two strikers against them and took the game to them.
“We created a load of opportunities and over the game we have had double the opportunities of Charlton.
“But the pivotal moment was when we missed a penalty kick.
“They could have had a couple of players sent off in the first half as they had two central defenders on bookings who then committed challenges after that.
“They were a bit fortunate to go in at 1-0 at half time. It was a great cross in and we didn’t stop the cross and they got in at the far post and got a goal against the run of play.
“Second half after we conceded the goal quite quickly we looked like the team that are in the position we are in at this moment in time.
“Charlton took the sting out of the game. They sat back, as you do at that stage in the game, and they kept the ball and the 2-0 advantage.”
