Celtic manager Ronny Deila has told the club's official Twitter account that the club's transfer activity is a 'never ending story'.
Deila has overseen four summer signings so far, bringing in OH Leuven goalkeeper Logan Bailly, Manchester City defender Dedryck Boyata, Manchester United right back Saidy Janko and Dundee United striker Nadir Ciftci.
Fans may be keen to see more new signings arrive ahead of the new Scottish Premiership season, and Deila was asked about his plans in the transfer market.
Speaking ahead of Wednesday's Champions League qualifier against Icelandic side Stjarnan, Deila told the official Celtic Twitter account that whilst he has a strong squad at his disposal, the search for players never really ends, displaying his proactive approach.

Which areas still need strengthening?
Celtic's four signings add options to Deila's squad, but there are still some positions in the Bhoys' squad that need some attention.
Signing a left back to compete with Emilio Izaguirre should be a priority for Deila, whilst the Norwegian could also look to add players in central midfield and out wide.
Centre back will become an issue again if Virgil van Dijk leaves the club this summer, even after signing Belgian defender Boyata.
There are no gaping holes in Celtic's side, allowing Deila to wait and see who becomes available, with over six weeks to go until the transfer deadline.
