Bastian Schweinsteiger was a notable figure missing from training today at Carrington. As reported he along with Jones and Herrera did not feature in the open training session held ahead of the game with PSV at Old Trafford tomorrow night.
Schweinsteiger has started to make a more notable impact in the middle of the park with his performances of late, and this has coincided with his return to full fitness. United fans will be hoping his absence is only precautionary rather than something more serious.
His crucial shot at the weekend which went in via Troy Deeney secured vital 3 points for the title chasers and with the absence of Carrick, Van Gaal will want to ensure his German commander is available for the crucial games ahead.
United know victory tomorrow night will guarantee qualification for the knock out stages and they can then concentrate on the busy period to come over Christmas.
The return of Rooney and Martial will be a big boost, after having only Depay as a recognized attacking threat on Saturday. It will be interesting to see if Van Gaal will risk both tomorrow night, or if he will be more cautious with the top of the table clash against Leicester to come this weekend.
