Manchester United have been dealt an apparent injury blow, with manager David Moyes confirming that midfielder Shinji Kagawa has been suffering with sickness and could miss Saturday's Premier League tie against Newcastle.

24-year-old Kagawa joined the Red Devils from Bundesliga title hopefuls Borussia Dortmund last summer yet has failed to truly establish himself as an indispensable first-team regular since moving to Old Trafford.

While no-one has ever doubted his commitment to the cause, Kagawa has rarely been afforded the chance to fulfil his preferred role behind the striker and has spent much of the current campaign under new boss David Moyes as a rather isolated figure either on the substitute's bench or marooned out on the left-hand side of midfield.

Kagawa played very well indeed in that classic 'no.10' role in the 5-0 demolition of Bundesliga outfit Bayer Leverkusen that secured Manchester United's progression into the next round of the Champions League, yet was substituted after 58 minutes after a disappointing showing in the 1-0 defeat to Everton on Wednesday evening.

Manchester United's next test following that dismal loss to Moyes' former employers comes against Alan Pardew's Newcastle United at Old Trafford on Saturday. It looks, however, as if Kagawa is a doubt for that match.

"He's had a sickness and has been unwell. I'll see how he is tomorrow. I hope he's available." Moyes was quoted by Manchester United's official Twitter feed in a press conference on Friday afternoon.

Earlier today, rather worrying reports surfaced suggesting that the Japan international required attention from paramedics after apparently suffering breathing difficulties following Wednesday's game.

It is unclear at this stage if the illness described by Moyes that could rule him out of action on Saturday is linked to that concerning aforementioned incident.
