Mikel has fallen out of favour with Antonio Conte’s since the Italians appointment as manager in the summer.
The 29-year-old, who has just six months left on his current deal, is yet to play a single minute of football this season.
And Igalho admits he would love to see his Nigeria team-mate choose Vicarage Road as his next destination.
Igalho told SuperSport: “I will like it if Mikel join me at Watford.
“He is my captain at the national team. Apart from that he is a very good player, very talented.
“I have played with him and against him, he is a very good player.
“There is no team in the Premier League that will not want to have such a player.
“I am happy I have played with him so I will be very happy to have him in my team.”
