Merson believes the pressure is on at Manchester United ahead of the season opener at Old Trafford.
He told Sky Sports: “This will be a good game. Pressure is on at United after not a great pre-season.
“This should be perfect for Leicester as United will have a go and they can be caught on the counter-attack, but they’ll miss Riyad Mahrez.
“I just think Mourinho will find a way to get off to a winning start.”
Merson predicts a 2-0 win to United.
