Slavisa Jokanovic claimed he said "nothing" at the interval after Watford produced a second-half comeback to recover from 2-0 down and beat Blackpool 7-2.The Hornets were in trouble at half-time after poor defending had allowed Andrea Orlandi and Steve Davies to put the basement side two goals up at the interval.
But once Odion Ighalo had reduced the deficit within two minutes of the restart, the Hornets took complete control as the Nigerian striker netted three more times and Troy Deeney, Matej Vydra and Gabriele Angella all scored in a stunning turnaround.
Asked what he had said at the interval, Jokanvic replied: "Nothing. At half-time we decided to put one midfielder more on and play with one defender less. I didn't speak so much at half-time.
"I explained if we're going to try and play some football and make some passes and fight all together we can resolve this problem.
"Really I didn't speak so much - but I believed we could change our situation.
"We scored many goals, but what's more important is probably the first goal that we scored [two minutes into the second half].”
The head coach singled out the four-goal contribution of Ighalo for praise.
Jokanovic continued: "He scored four goals, he played a very good game, he's working very hard and this is how he can help us, how he can help himself, how he can help the supporters and how he can help his family.
"He's always working very hard and in the three months sometimes I use him, sometimes not but always when I use him when he completes the game or [I bring him on] at half-time or [for] 10 minutes he's always working well like a professional football player and an adult."
Jokanovic brought on new signing Ben Watson at the start of the second half, in place of Tommie Hoban, and conceded playing Vydra in a deeper role had not worked.
He explained: "It's the second time where I gave Vydra a little bit of a chance as a midfielder and not a striker and he showed us he's a striker and not a midfielder - but it's my choice.
"Before the game I decided to put Vydra in this position because Watson arrived yesterday, Gianni Munari has a hamstring problem and can't be with us and the only player who can play in this position is George Byers.
"I decided to use Vydra but I decided to put in one more midfielder to make Vydra a little bit more of a striker and a little bit less of a midfielder.
"I know Watson but yesterday was the first time I've worked with him and today he did a good job for us in the second 45 minutes."
