Leicester, Tottenham, Arsenal and Manchester City are all fighting for the title.
Ighalo said: “I think the four teams at the top stand equal chances of picking the EPL title."
Ighalo has faced all four of the title chasing teams, and has been beaten by all of them this season.
Spurs and Manchester City have done the double over Watford, whilst Leicester await this weekend and Arsenal a few weeks later.
Many believe that Leicester will still collapse, despite them leading the league, and will hand the table to one of Spurs, Arsenal or City.
However, the Foxes are in the best position, and they keep increasing their lead on their rivals even when not picking up great results.
This midweek round of fixtures was the best example of Leicester’s good fortune, as many believed they would be caught up by Spurs on Wednesday.
The Foxes could only draw against West Brom on Tuesday, but then the three other top four teams all contrived to lose the following evening.
They gained one point on their closest rivals, and Leicester will believe that they can pick up three points this weekend - when they take on Ighalo and his Watford teammates at Vicarage Road.
