In June, the talismanic midfielder’s agent played down the chances of Wanyama joining the Saints after the south coast club were reported to have launched a bid.
But Kayal is confident he can fill the African’s void should he seal a move away from Parkhead.
“I’m happy if the gaffer says I’m the man to come in and play all the games,” Kayal told the Daily Record.
“Victor’s a great player, and a great friend to me, too.
“We play together in the midfield and he has proved himself in the Champions League that he’s a great player at the highest level.
“If he goes, we’ll be losing a great player and a great friend and I’ll work hard to get into the team. I just want to come back and show everyone the real Beram Kayal.
“I’m 100 per cent and can play all the games and give my best.
“But I don’t decide whether the club buys players or doesn’t buy players because that’s the gaffer’s job.”
