Jenkinson feels Arsenal need to focus on delivering consistent performances from their own remaining nine matches, following the win at Swansea, rather than worry about the shortcomings of others.
Speaking to Arsenal Player, Jenkinson said: "We just need to concentrate on ourselves. Other teams are going to drop points.
"We want to win every game and we are capable of doing that.
"Our form hasn't been bad. It can be better of course. From now it's just about now until the end of the season. That's going to be what makes or breaks us, so it's almost like a little season in itself.
"We just need to get on a good run and keep it going. If we do that, we'll end up where we need to be."
