Rookie boss Lee Johnson saluted his team's achievement after Oldham guaranteed their League One safety with a 2-1 win against Crawley.

Oldham were in the relegation zone when Johnson, at 31 years old the Football League's youngest manager, took over the Boundary Park hotseat from Paul Dickov.

But they have earned 14 points from his eight games in charge and grabbed their latest victory with a last-gasp goal from Jean Yves Mvoto.

Johnson said: "It wasn't a vintage performance but the lads have put in a monumental effort this week. I knew they would be leggy but we stuck to the gameplan and were defensively sound.

"I'm pleased with the run we've had since I came here and it's fantastic to be safe."

Matt Smith fired Oldham in front after 56 minutes, bundling through to the edge of the box and unleashing a low shot into the bottom corner of the net.

Crawley levelled 13 minutes from time when a short corner routine ended with Mark Connolly converting a simple header from point-blank range.

The Latics' winner arrived in stoppage time as Mvoto met Jose Baxter's deep free-kick and headed home from four yards out.

Crawley's top-six chances are over and manager Richie Barker challenged his side to build on a promising first season in League One.

He said: "To reach our 44th game and still be fighting for something was a testament to everyone."
