Sunderland have joined the battle for Celtic striker Gary Hooper.

The Journal says the Wearsiders are also tracking Hooper. Sunderland are looking to sign two forwards this summer and have an interest in Hooper, who is also a target for Norwich and Hull City.

Celtic are aware that they face losing some of their brightest assets and Hooper, who is rated at around £5million by the Glasgow giants, is one of the striking possibilities being explored by Sunderland.
