The Red Devils head into this weekend’s round of fixtures flying high at the top of the Premier League table after having won all three of their opening games.
Jose Mourinho’s men have scored 10 goals without reply in their Premier League openers against West Ham, Swansea and Leicester.
Manchester United are now preparing to take on the Potters at the bet365 Stadium on Saturday evening as they look to continue their strong start to the new campaign.
However, Merson is expecting to see the Red Devils be made to work hard for the three points against the Potters this weekend.
Merson wrote in his column for Sky Sports: “I haven’t really bought into Manchester United so far this season. They won games by an impressive margin, yes, but I don’t think they’ve clicked yet.
“They scored three goals in three minutes against Swansea, West Ham were comfortable for 25 minutes before throwing the towel in and, as I said before, Leicester had good chances at Old Trafford where a top quality team would have punished them.
“United do look a better team than last year. They look strong, they look quick with plenty of pace on the break but I don’t think Jose Mourinho will see his side as the finished article. Maybe he will stick himself in goal after his performance in the #Game4Grenfell – just not for penalties.
“Joking aside, if they can go to Stoke and win then fair play to them. The bet365 Stadium has always been a hard place to go but I can see United edging it.”
Manchester United finished sixth in the Premier League and won the EFL Cup and Europa League last season.
The Red Devils are set to make a return to the Champions League group stage next week.
