Celtic have reportedly made a £5m transfer offer for defender Auston Trusty.

The Parkhead club are thought to be keen on the Sheffield United centre-back - who can also play on the left of a back four.

Yuki Kobayashi and Gustaf Lagerbielke have both left Celtic in recent days leaving a gap in the defensive ranks for Brendan Rodgers.

Former Arsenal defender Trusty, though, has been identified as a possible transfer candidate.

Sky Sports claim a bid worth in the region of £5m has been submitted to Sheffield United to try and land Trusty before the deadline later this week.

Trusty was a first-team regular for United last season in the Premier League but now could head to Scotland after the club was relegated to the Championship.

The 26-year-old has played for the United States on the international stage and has played twice for Sheffield United so far this season.

He was on the bench for the two opening Championship fixtures but played the full 90 minutes in a 1-1 draw with Norwich last weekend and started in the EFL Cup win over Wrexham.

It comes after Lagerbielke's loan switch to FC Twente was confirmed - with confirmation no buy clause is in the agreement.

“When I heard about FC Twente’s interest, I was immediately interested,” said Lagerbielke. “FC Twente is a club with a rich history and the team has achieved good successes in the last four years.

"After my conversation with the trainer, I got a good idea of ​​the plans and I wanted to go to FC Twente. Next season, I hope to play as much as possible, to finish as high as possible with FC Twente in the competition. Of course, I am also looking forward to the matches in Europe.”
