David Jeffrey is refusing to be lulled into a false sense of confidence ahead of Tuesday’s County Antrim Shield showdown with Cliftonville.
Linfield boast home advantage for the semi-final clash against a Reds side who have struggled to find consistency this season.
The Danske Bank Premiership champions sit six points behind the Blues after what has been a stuttering start to their title defence.
Cliftonville’s Gibson Cup credentials are already coming under scrutiny, but Linfield boss Jeffrey is under no illusions.
“Cliftonville are a quality side. They are excellent,” he said.
“To me, they are stronger this year with the signings they made during the summer, with the likes of Chris Curran coming in.
“Tommy (Breslin) has freshened them up and they are formidable, so Tuesday night is a big test.
“Cliftonville and Crusaders have well-established squads, when you compare them with the likes of Glentoran and ourselves. We have made massive changes during the summer and are rebuilding.
“Crusaders are very settled, and Cliftonville have strength in depth, so ourselves and Glentoran are working hard to push up there.”
