Manchester United send scouts to watch Celtic star

Manchester United have reportedly sent their talent-spotters to monitor the progress of Kieran Tierney during tomorrow's Scottish Cup semi-final against Rangers.

The Scotland international has been linked with United for a while, and the Red Devils appear to be pondering over a summer move for the left-back.

According to The Mail, United will have scouts watching the performance of Tierney during this weekend's Old Firm derby between Rangers and Celtic at Hampden Park.

Tierney has supposedly been earmarked as a replacement for Luke Shaw, whose association with United is likely to conclude at the end of the current campaign.

Shaw has received plenty of criticism during Mourinho's reign at Old Trafford, and the Englishman could be sold in order to recoup funds to sanction Tierney's move.

Aside from Tierney, United are also keeping tabs ob Alex Sandro and Danny Rose from Juventus and Tottenham Hotspur respectively, though the club may have to spend excess of £50m for either player.
