West Ham will go in search of their first win at Old Trafford since May 2007, when a Carlos Tevez strike gave Alan Curbishley's side victory and preserved their Premier League status.
Dear, who famously scored five times in nineteen minutes for West Ham during a 6-1 thrashing of West Bromwich Albion in Apri 1965, was quick to point out that his old side had fared well in the transfer market themselves this season: "Joe Hart and Zabaleta are great signings which will bolster the team defensively".
Romelu Lukaku will be tasked with spearheading United's attack following his £75m move from Everton and Mourinho believes it is imperative that other players chip in with goals.
"And last season that didn't happen much - we were focused on the goals that our striker was scoring and when he was not scoring, the team was a little bit in trouble to win matches".
With the London Stadium now being used for the IAAF World Championships, West Ham's trip to Old Trafford will be the first of four away games to open the new domestic campaign.
There were fluency issues last season, perhaps left over from the Lous van Gaal era. There are two different people with Mourinho.
"We had lots of dominance at home, lots of chances, lots when the match should be two or three nil and in the end was 1-1. It will not be easy but we travel to win the game".
In his second year at Porto, Mourinho announced himself on the world's footballing stage by delivering the Champions League to the Portuguese club in the 2003-04 season, earning himself the Chelsea job.
Romelu Lukaku, Victor Lindelof and Nemanja Matic have so far arrived this summer, but Mourinho always meant to make four acquisitions.
"Jose Mourinho, nearly incredibly, has never lost a home match on a Sunday in any competition during his long managerial career and I would be surprised if the Hammers caused a shock this weekend".
"I just think he was very clear showing what he did a year ago was not enough for him".
"So I'm convinced I have - not just the hope - but the conviction that our second season, in terms of the quality of our team, is going to be better".
While United had to deal with playing regularly on Thursdays and Sundays on their way to winning the competition in Stockholm, Chelsea eased to the Premier League title with no European football to worry about - and neither did Liverpool, who took fourth spot as United finished sixth.
"So between the players we lost and the players we got, I think we are in a similar situation".
"It was very clear by showing what he did a year ago was not enough for him", he said. "This group of players is going to stay for a long time at Manchester City". Okay, some will have the luck to play on Tuesday or Wednesday, or Saturday or Sunday.
