David Jeffrey hailed what he described as a “big day” for Linfield after the Blues secured a 3-1 win over league leaders Cliftonville on New Year’s Day.
The champions kept their faint title defence alive with a rousing display against the Reds.
Matthew Tipton (2) and Michael Carvill got the crucial goals, with Liam Boyce on target for the visitors.
The defeat means Cliftonville’s lead at the top of the Danske Bank Premiership has been cut to six points over second-placed Crusaders.
Linfield are a further four points adrift in third, but Cliftonville can boast a game in hand.
“This is a big day for us, and we fought tooth and nail for this,” Jeffrey said.
“It was fantastic to beat Glentoran here on Boxing Day, and it was fantastic to beat Cliftonville here today.
“We have sent our fans home happy.
“We played well today and deserved our win. I don’t think anyone could argue about us winning today.”
Ciliftonville boss Tommy Breslin believes his side failed to capitalise on a number of decent goal scoring opportunities at Windsor.
“I am disappointed,” he said.
“I thought we played well in spells, and when we popped the ball about we opened them up.
“We had four or five really good chances, but Alan Blayney has pulled off some great saves.
“We should have taken them, and we were poor defensively today. We gifted Linfield three goals.”
