Kelvin Wilson was one of the players Paul Jewell had a bid for rejected last weekend.

The Celtic centre-back was targeted by Ipswich last week but their initial bid was rejected by the Scottish Premier League champions.

The 26-year-old was left out of Celtic’s Champions League qualifier on Wednesday night at HJK Helsinki with his old club Nottingham Forest also said to be interested.

We understand Town are considering a second bid for Wilson, but that Jewell is unwilling to go much higher than his initial offer.

Wilson made 20 starts for Celtic during the 2011/12 season after signing for Nottingham Forest, where he played alongside Ipswich new boy Luke Chambers.

Speaking on Wednesday night after the pre-season win at Colchester United, Jewell revealed: “I still want to bring in a few players.

“It’s been frustrating because I know we need to strengthen. We’re a bit short of me being happy with the squad, but I’ve got to have patience and make sure those that do come in are the right ones.

“We had a couple of bids rejected over the weekend and whether we go back in for them remains to be seen. We’re working exceptionally hard to improve the squad.”

A fourth centre-back, alongside Chambers, Tommy Smith and Damien Delaney, remains a priority for the Blues boss.
