Thomas Frank insists Ivan Toney is happy at Brentford despite interest from Arsenal and Chelsea.
Standard Sport understands the Bees are willing to sell the striker for around £80m in January, with Toney set to enter the final 18 months of his contract.
The forward has already made it clear he wants to move to an elite club after signing with super-agent Jonathan Barnett in a bid to fulfil that dream.
Brentford hope a foreign club could enter the mix to further drive up the price but London rivals Arsenal and Chelsea are currently the frontrunners.
Speaking ahead of Brentford's match against West Ham on Saturday, Frank told a press conference: "I want him to stay. Ivan is happy to stay.
"He is happy at the club. What happens in the future is impossible to guess about.
"He's a top player, one of our most important players, if not the most important last year. Any player that can score 20-plus goals in the Premier League are very, very important.
"Ivan's skillset in terms of finishing abilities with his left and right (foot), heading and his composure in those moments and his link-up play and his presence, character, is a very good package.
"It's not (up to) me to put a price tag on him, it's down to the club. But I'm happy with him, I hope he plays here forever and I'm the coach."
Midfield trio Mikkel Damsgaard, Keane Lewis-Potter and Josh Dasilva resumed light training this week. Damsgaard and Lewis-Potter are likely to return to practising with the first-team next week.
Brentford go into this weekend looking for a third successive win, having seen off Burnley and Chelsea in the last fortnight, and the Bees have beaten West Ham in all four of their Premier League meetings.
But Frank added: "West Ham are a very good side with a very good and experienced manager (in David Moyes).
"They've had a good start to the season, they top their group in the Europa League and are in the quarter-final of the Carabao Cup.
"They are a strong opponent but we trust ourselves and believe and if we top perform, we have a good chance of winning."
