Everton to Reportedly Rival Manchester United, Tottenham in Kieran Tierney Chase

Everton are reportedly ready to rival the likes of Manchester United and Tottenham Hotspur in the transfer chase for Celtic full-back Kieran Tierney this summer.

According to David Maddock of the Daily Mirror, new Toffees boss Marco Silva wants to add a left-back to his squad and has made the Scotland international a priority target; a £25 million offer will reportedly be made.

However, Everton are unlikely to have things their own way in their attempts to get the player to Goodison Park.

"Celtic are reluctant to let Tierney go, but a big-enough bid could persuade them to sell, with the lifelong Celtic fan now thought to be keen to test himself in the Premier League," Maddock said. "Atletico Madrid [are] interested, and also Spurs and even Manchester United monitoring his situation as they look to strengthen in that position."

Tierney is one of the most exciting young players in Scottish football, offering an irrepressible presence down the left flank for Celtic.

As the Scouted Football Twitter account noted, having accomplished so much with the Glasgow giants, the left-back appears ready to make a step forward in his career:

The 21-year-old made his debut for Celtic in 2014 and cemented his status as a first-team regular during the 2015-16 campaign, ousting fan favourite Emilio Izaguirre from his starting berth. Since then, the youngster hasn't looked back.

Celtic have dominated Scottish football in recent years, and under manager Brendan Rodgers, the full-back has provided a key attacking outlet for the Bhoys. Tierney is full of energy, makes penetrating runs forward and tends to make smart decisions in the final third.

As the Daily Record noted, Rodgers said Tierney may be on the move sooner or later:

While Everton's need for a left-back is clear, with Leighton Baines reaching the twilight of his career, both United and Tottenham would benefit from upgrades in the position too.

Spurs have Ben Davies and Danny Rose competing for the spot, although the latter has long been linked with an exit from the north London club, with John Cross of the Daily Mirror reporting as much. At Old Trafford, Ashley Young was used in the role in the main last term, with manager Jose Mourinho seemingly unsure about Luke Shaw.

Journalist Tom McDermott suggested earlier this season that United should be aiming higher than Tierney:

While he's played in the UEFA Champions League, Tierney is untested in one of Europe's elite divisions. The Premier League would pose different challenges to the youngster too, especially in terms of his defensive duties.

Mmoving to a club like United or Spurs, where the pressure to perform immediately would be enormous, may be too big a jump for Tierney. It means Everton may have an edge in the pursuit of the player, although Celtic will surely do all they can to keep a man who signed a six-year deal with the club last season.
