The Senegal international has been in sparkling form this term, with his performances helping to propel the Hammers into the top half of the Premier League.
Diamé reportedly has a £3.5m release clause in his contract after completing a switch to West Ham from Wigan Athletic during the summer.
It has prompted interest from a host of top-flight clubs, and Wenger has taken not of Diamé’s match-winning displays, particularly in a 3-1 victory over Chelsea.
“He has a great presence and can drive the midfield,” said Wenger.
“I’ve seen him in games where he’s had a big impact, for example against Chelsea. ”
Last week, West Ham manager Sam Allardyce played down the chances of Diamé completing a possible switch across London to the Gunners.
“You are always worried about losing players but we have not had a bid from Arsenal for Diamé. I can’t see where he would fit into their side,” said Allardyce.
