Ange Postecoglou will be hoping to have a busy summer at Celtic Park.

With the Champions League group stage just around the corner, Postecoglou will need to do some more savvy spending in the market.
Cameron Carter-Vickers and Jota looks set to return to Glasgow's east end on permanent transfers, but that will only be the start.
A left-back to provide competition for Greg Taylor also looks to be a key area this summer.

The left-back had been mentioned as a potential recruit the summer as competition for Greg Taylor.
However, the Swedish chief admits he has been surprised by the lack of movement so far.
Sparking to Expressen , he said: “We have some players who have done well and we expect there to be interest in these players during the transfer window.
“He is a player who has delivered at a very high level. He has had high peaks during the year and it is a bit surprising that there is not more interest in Otieno."
