Manchester United's pursuit of Celtic left-back Kieran Tierney is reportedly set to intensify, as they are expected to make a formal offer for him.
According to David McDonnell of the Mirror, the 20-year-old is rated at £25 million, and United will step up their interest in him with a bid in the coming weeks, having scouted the youngster and been impressed with his performances.
His versatility appeals to manager Jose Mourinho, as he can also provide cover at centre-back or right-back, and he's viewed as better value for money than Tottenham Hotspur's Danny Rose, United's other top target, who is expected to cost twice as much.
