Manchester United captain Wayne Rooney said it was a "proud moment" for him after equalling the club's goal-scoring record set by Bobby Charlton when he netted his 249th goal for United Saturday.
Rooney could now break the record against Hull City in Tuesday's League Cup semi-final first leg and United manager Mourinho said: "I think the best day for him will arrive".
Rooney has now hit out at the extensive coverage given to the incident within the United Kingdom media, accusing some outlets of prioritising the incident over his latest goalscoring landmark.
Rooney has secured his place in Manchester United history and Old Trafford's hall of greats with his record-equalling goalscoring feats.
Interestingly, Rooney in 2015 bettered Charlton's England scoring record of 49 goals and now has 53 to his name. "To be up there with Sir Bobby in terms of goals is a huge honour".
"Hopefully I'll be up there on my own soon!"
Reading boss Jaap Stam, making his first return to Old Trafford as a manager after his hugely successful time as a United player from 1998 to 2001, also paid tribute to Rooney.
Manchester United are through to the fourth round of the FA Cup thanks in no small part to Wayne Rooney's heroics.
Martial was United's top scorer last season under Louis van Gaal, but Mourinho admitted earlier this season that the 21-year-old was perhaps less suited to his style of play. Rooney was linked with a move to Chelsea throughout the summer of 2013 and, as opposed to denying the rumours, the only statement he made at the time was to deny reports claiming he had changed his Twitter bio to remove "Man United player".
One more goal will put him top of an impressive list of club icons.
United manager Jose Mourinho said: "A more special day will arrive".
"If you look back at all the games he's played in and all the goals he's scored for the club, it's fantastic". He would score important goals and wheel away kissing the badge on his shirt.
"It's awesome. Everyone knows who Sir Bobby Charlton is and what he means for the history of the club and English football".
Marcus Rashford, who wasted several opportunities after being given a rare start up front, sealed United's eighth successive victory with two quickfire goals in the closing stages. "But I was really happy with our attitude".
When asked about Rashford and Martial, Blind said: 'They are great, great players so I think for any defence it's hard to play against them.
