Jennings has netted six goals in his last five games for the Silkmen and can now play in their fourth round qualifying game with Vauxhall Motors.

“Connor started slowly but has come back to score some goals. “He’s found it very difficult breaking through to our team, but maybe he will come back as a different player, a different personality.
It’s certainly benefitting him playing games.”
