Crawley Town captain Josh Simpson says keeping striker Matt Tubbs at the club this month will send a message to the rest of League Two.
The Reds rejected two bids for the 27-year-old forward from League One side Bournemouth this week.
Simpson, 24, told BBC Sussex: "We know there's going to be clubs coming to watch certain players.
"It's no surprise people are watching Tubbsy but we want to keep our best players and get promoted."
Crawley currently sit top of League Two and have reached the fourth round of the FA Cup, knocking Championship outfit Bristol City out of the competition in the process.
"We've got a really high calibre of player in the dressing room," Simpson added. "Results don't lie.
"Everyone wants to beat us. We're on a pedestal and they all want to knock us off.
"But we've got a few tough games coming up. We've got to take each game as it comes."
