Celtic are monitoring Philadelphia Union centre-back Mark McKenzie.

Last week, Sky Sports News reported that representatives of centre-back Kristoffer Ajer had asked the club for a valuation of their client, ahead of a potential move away from Parkhead.
The summer transfer window will run for 10 weeks from July 27 and close at 11pm on October 5.
