Manchester United manager Jose Mourinho has confirmed that midfielder Marouane Fellaini suffered a "bad" back injury in his side's 1-0 victory over Hull City on Saturday, 27 August. He started his third consecutive match of the season against the Tigers at the Kingston Communications Stadium and is set to be on the sidelines after the latest setback.

Marcus Rashford, who came on from the bench in the 71st minute, scored the late winner as his stoppage time goal made the difference between the two sides. After the match, the former Inter Milan and Real Madrid manager confirmed the Belgium international's setback.

The club football will take a break as the players will now join the international squad for the upcoming matches with the national team. Fellaini, who was picked by new Belgium manager Roberto Martinez, will travel with the Belgium squad.

"I saw the way Fellaini and the two central defenders controlled everything long, high and short," Mourinho explained, as quoted by

"But I can't play Fellaini for some time. He has a muscle injury in his back. He will fly [with Belgium] but it is bad."

United will host Pep Guardiola's Manchester City in the next league clash at Old Trafford after the international break on 10 September. It should be seen whether Fellaini will be fit to face the derby rivals in front of the home fans.

Should the former Everton star not be fit for the clash, Mourinho has several options in that position. The list includes the likes of Michael Carrick, Ander Herrera and Morgan Schneiderlin.

The Portuguese tactician has refused to suggest that United were lucky to score the late winner against Hull. Mourinho claims his side deserved to score the goal and grab three points in the latest fixture.

"I know when we score late people will speak about a bit of luck but the reality is we deserved it, especially in the second half. We were so dominant, so intense in our rhythm and our attacking wave and I always believed the goal would arrive," United manager said, as cited by the club's official website.
