Manchester United boss Louis van Gaal says striker Radamel Falcao still needs to justify his place at Old Trafford. Van Gaal said: "If a player costs £95m or £5,000, it doesn't make any difference. You have to prove yourself."
The Colombia international was left out of United's squad for their 1-0 home loss to Southampton last Sunday.
United have an option to activate a £40m buy-out clause for the striker, who earns £265,000 a week.
The Dutchman added: "He has to prove himself, that we have agreed. We have made this deal and everything is clear and it is not the end of the year [the duration of his loan spell] so he has the chance for that.
"For the manager it is the quality of the training sessions, the quality in his performances and matches and he has to compare [favourably].
"A player of £95m has to prove himself also. Maybe he has less motivation so I have to be like that."
