"We are on course and have a chance," the Blues boss said after the 4-0 win at Roots Hall.
"Fifteen players have gone since last season and we have brought in a lot of younger players.
"It has been a huge turnaround, so we are delighted it has clicked and it can only get better.
"It was a potential banana skin coming here because we are top and they are bottom, so it was a good win."
