After sealing their Premier League return with a 1-0 victory over Aston Villa in the Championship playoff final on Saturday, Fulham's attention will already be turning to next season, with the future of several loanees uncertain.
However, if the Midlands outfit were to secure promotion on Saturday they would need further additions to adequately equip themselves for the gruelling nature of the Premier League.
Owls boss Jos Luhukay had earlier stated that it was up to Clare and fellow under 23s player George Hirst, who is also out of contract, whether they wanted to stay.
It is expected, however, that both will leave Wednesday when their deals run out.
With Fulham getting promoted to the Premier League, it would be hard for Tottenham or Manchester United to secure the services of Sessegnon this summer. We need to be fearless, we need to make investment, we need to spend money to survive or to make a more important step.
Villa were unable to break down a Fulham side which played the last 20 minutes with ten men after Denis Odoi's sending off. His lunge on Cairney just outside Fulham's own area was late and ugly and could have been a red card but was only yellow.
According to the Birmingham Mail, Aston Villa are looking to sign Moussa Marega after the Porto striker's asking price was dropped to £26 million.
"I'm in charge of a really great club and I've enjoyed every minute of it", he said. Ryan Fredericks certainly seemed to let the occasion better of him when he stamped on Jack Grealish on the half-hour mark.
Villa's only avenue of attack seemed to be through the slick-haired Grealish, who had spent much of the half on the floor as the Fulham players took turns hacking him down.
It defeated Derby County in the playoff semifinal on a 2-1 aggregate and features the likes of USA defender Tim Ream and rising teenage English fullback Ryan Sessegnon. "We must adapt and be clever, we must not make one step back".
The 22-year-old and the Villa fans were incandescent when handball appeals against Odoi were ignored - anger that bubbled over as he launched into an overzealous challenge on Cairney that led to a booking and on-field commotion.
