|10/1||Chelsea are 10/1 with Bet365 to beat Man Utd 2-1
"You look at what's happened off the field, what's happened on the squad, internally what can happen, but also it's form as well," McClaren told BBC Radio 5 Live.
"John Terry also is progressing in age and Chelsea are rotating him, so it's purely on form and Roy Hodgson looking ahead to the future.
"So if you look ahead to the future will John Terry in one, two, three, four years be involved in that?
"I think Roy Hodgson has a decision to make as to whether to go for the future or whether to win in the short term."
Terry has made 78 appearances for England, captaining the side on 34 occasions.
