Manchester United manager Jose Mourinho was honoured to give first-team debuts to Axel Tuanzebe and Joel Pereira on Sunday.

Promising defender Tuanzebe replaced Timothy Fosu-Mensah in the 68th minute while young goalkeeper Pereira came on for Sergio Romero with 10 minutes remaining of United's 4-0 win over Wigan Athletic in the FA Cup fourth round.

"For Tuanzebe and Joel, it was their first match and it's always a nice moment for every a player, a moment that stays in their career," said Mourinho.

"So it was nice for me to give them the opportunity, (but) it's not my work.

"The work was made in the Academy, where the players have been since they were young kids; in Joel the work was also done in Portugal, where he played for six months with Belenenses.

"So it's not my work at all – I'm just the guy that have them the opportunity."
