"It's been incredible", said Fonte in response to questions over West Ham's summer transfer business.
This was part of the remit - scoring goasls against stubborn teams who park the bus when they rock up to Old Trafford, with the draw at home to the Hammers past year a case in point.
The Blues need reinforcements and signing a left back as competition for Marcos Alonso is high on the club's agenda.
He achieved the feat at Porto, Chelsea twice, Inter Milan and Real Madrid, with the only exceptions to the rule being his first two management roles, at Benfica and Uniao de Leiria, where he lasted less than a season in both cases.
SKOPJE, MACEDONIA - AUGUST 08: Victor Lindelof of Manchester United warms up prior to the UEFA Super Cup final between Real Madrid and Manchester United at the Philip II Arena on August 8, 2017 in Skopje, Macedonia. In Mourinho's last Premier League triumph, the Blues from London won it easily, trotting towards the finish line since February.
Now, they have re-enforced, and you get the feeling, that if they come off then this is a team that is going to fly.
It wasn't a great day for all United's signings and Victor Lindelof watched the game from the stands along with Michael Carrick, Luke Shaw and Ashley Young.
Moments later Paul Pogba fired in the fourth after he was slipped in by Martial to complete the rout.
The veteran striker would be unlikely to even feature until the new year due to the severity of the injury sustained last season playing for United, but it is his presence that Mourinho wants at Old Trafford.
Eric Bailly and Phil Jones, the centre-back pairing against West Ham, did nothing to suggest they won't start again at Swansea next week.
As for Tottenham, they've yet to add anyone, but they didn't do too badly past year with the players that they have now.
West Ham have done some interesting business of their own, signing Marko Arnautovic, Pablo Zabaleta and the former Old Trafford favourite Javier Hernandez.
There are weaknesses with all of them, whether it's in attack or defence, and quite frankly, a lot of them are much of a muchness. West Ham may struggle on Sunday but Hernandez will have a point to prove against his former club.
