Tigers chasing Thomas Hull have made a revised bid for Stoke ‘crossing machine’ Sorba Thomas. The Tigers have already had a £7m offer rejected for the Wales international winger with Stoke looking for around £10m.Thomas was Stoke player of the year and made it into the divisional team of the year last season, contributing 13 assists, 10 goals, plus a couple of forced own goals.Indeed, analysts identified that 26-year-old Thomas supplied 410 crosses in his 45 league matches. The next highest in the Championship was Millwall’s Femi Azeez with 294.He added to his tally last night as Stoke took on Hull in the Carabao Cup only to lose on penalties.Afterwards Hull City boss Sergej Jakirovic, quizzed on his interest, said: ‘I know everything about Sorba Thomas from the Championship, he’s a difference maker, and he’s a very good player.’Hull have also enquired about Fabio Carvalho at Brentford but they want the midfielder to stay.The Premier League new boys have agreed to sign Union Berlin forward Ilyas Ansah for around £21m.

Johnstone has emerged as a potential option.The 33-year-old England international is at Wolves but his future at Molineux is increasingly uncertain following the club’s relegation to the Championship and subsequent changes to their goalkeeping department.Johnstone underwent shoulder surgery towards the end of last season, which ruled him out of the final matches of the campaign and disrupted his pre-season. However, he has been back training for several weeks, has regained full movement in the shoulder and is effectively back to full fitness.Despite his return to fitness, there are significant doubts over whether Johnstone features in new Wolves boss Cesar Peixoto’s long-term plans.Jose Sa returned to the side following his involvement at the World Cup, while Wolves have moved to agree a £1.3million deal for Sporting Lisbon goalkeeper Joao Virginia and are in talks to bring back John Ruddy, another indication that the goalkeeping order at Molineux is changing.Although Dan Bentley has recently departed for Coventry City, Wolves have openly spoken about wanting another goalkeeper and would be willing to allow Johnstone to leave.The arrival of Virginia leaves Johnstone facing an uncertain battle for football and little evidence of a long-term future at Wolves, potentially opening the door for Celtic.Johnstone would bring considerable experience to Celtic Park. The former Manchester United academy goalkeeper has made more than 350 senior appearances during spells with West Bromwich Albion, Crystal Palace, Aston Villa and Wolves, while he has also represented England at senior level.At 33, he could offer Celtic an experienced and proven presence at a time when the club are looking for greater stability following the extraordinary collapse against LASK.With the transfer deadline approaching and Johnstone now nearing complete match fitness, it could be a situation that develops quickly.Celtic need a response after their Champions League humiliation and Johnstone needs regular football. A move to Glasgow could potentially suit both parties.Wanted man Morato Nottingham Forest defender Morato is wanted by Roma on loan.
