Brendan Rodgers has been looking to bring Jonny Hayes to Celtic for much of the summer so far.
According to a report on TeamTalk, Celtic are growing concerned about missing out on Aberdeen’s Jonny Hayes to Sunderland.
Celtic have been tracking Hayes for much of the summer so far, but have been unable to agree a price to date.
However, the Bhoys are hoping to rush through a deal for the 29-year-old attacker now, as they fear he could join Sunderland.
Aberdeen boss Derek McInnes is expected to take over at the Stadium of Light, and it is understood that he will make Hayes an offer to join him on Wearside.
Celtic are determined not to allow McInnes the chance at a reunion, and are now intending to step up their interest.
Celtic are thought to have offered around £1.2 million to take Hayes so far, with Brendan Rodgers keen to bring the attacker to Glasgow.
Hayes scored 11 goals and claimed 24 assists for Aberdeen over the past campaign.
