The west Londoners have endured a difficult start to their top-flight campaign after winning promotion last season, losing each of their first four matches.
They got on the board with a 1-1 draw against fellow strugglers Sheffield United on Sunday, with summer signing Ademola Lookman opening the scoring before Billy Sharp’s penalty levelled the scores.
“I thought in the second half we were exceptional,” Parker told the BBC. “In the first half, we came with a bit of plan, we needed to tinker things at half-time and the players responded very well.
“The second half, I saw a dynamic team, a team that could create chances and I was pleased overall in that sense. There is still plenty of learning and plenty of improvement to do – a young team with young players coming in and making their debuts.
“The team is going in the right direction, not just today. The last performance as well was very pleasing. From where we were in the first three games where we had our struggles we appear to be coming out of that and pushing in the right direction.”
