Raya has turned down multiple offers to extend his stay at the Gtech Community Stadium, with his current deal set to expire at the end of next season, and Tottenham are among the clubs keeping tabs on the situation as they consider replacements for Hugo Lloris.
Frank talked up the Brentford number one alongside top scorer Ivan Toney amid heavy speculation surrounding both players’ futures.
“There is no doubt that David (Raya) is a case where there is one year left and we will see what will happen. We’re very happy with David here,” Frank said.
“Everyone knows he is a £40m-plus goalkeeper if anyone is interested and we are prepared just like in any position.
“There is a possibility he’ll leave this summer maybe, for the right price, and if that happens then of course we need to be prepared.”
Toney’s 20 goals in the Premier League so far is an improvement on the 12 he got in the previous campaign as Frank lauded the striker’s career path and ability which landed him a 2020 move from Peterborough.
“I love Ivan and I think it’s fantastic what he has achieved here and there’s more to achieve here for him. I’m really really happy he’s a Brentford player,” the Bees boss added.
“He did well in League One, then he did well in the Championship and got promoted, he got 12 Premier League goals last year, now he’s on 20, hopefully getting even more, what is the limit? I think he has good potential.
“I know he’s not 22 (Toney) but look at some of the best strikers in the world, (Robert) Lewandowski, (Karim) Benzema, they seem like fine wines getting better, they know how to be in good positions. I think Ivan will only get better and better.”
