Tottenham Hotspur and Borussia Dortmund are reportedly among the clubs interested in signing Kristoffer Ajer from Celtic in the summer transfer window.

Kristoffer Ajer is already at a great club in Celtic, and the Norway international defender is reportedly on the radar of some other top teams in Europe, including Tottenham Hotspur.
According to TEAMtalk, German club Borussia Dortmund, as well as Premier League trio Tottenham Hotspur, Watford and Southampton are interested in signing Ajer from Celtic in the summer transfer window.

The 19-year-old, who cost Celtic £500,000 in transfer fees when they signed him from Start in 2016 according to ESPN, has established himself as a key figure in Brendan Rodgers’s side this season.
Ajer could have a tough decision to make if Dortmund, Watford and Southampton all make offers for him in the summer transfer window, but the youngster should not hesitate to move to Tottenham if the North London club come calling.

Tottenham manager Mauricio Pochettino enjoys working with young players and improves them, and the way Davinson Sanchez has established himself as a regular for the North London outfit and has improved this season should inspire Ajer to make the move to Spurs.
True, the teenager is playing regularly for Celtic at the moment, but the standard of football in Scotland is not as good as that in the Premier League.
Ajer will improve if he faces top-quality attackers week in and week out, and playing with world-class footballers such as Hugo Lloris and Jan Vertonghen will only make him better.
