Sporting CP head coach Silas could not confirm if Manchester United target Bruno Fernandes played his last match for the Portuguese club on Monday.
The Red Devils had been eager to sign the Portugal international although as reported by Goal, any potential move is now off after the Primeira Liga side refused to budge on their €80 million (£68m/$89m) asking price.
Indeed, Fernandes has continued to feature for Sporting despite the speculation over his future, with the 25-year-old captaining his side in their 1-0 win over Maritimo.
Despite it appearing that Fernandes will remain with the Portuguese side until at least the summer, Sporting head coach Silas was unwilling to confirm that the midfielder is definitely staying put.
"I can't confirm it [if Fernandes made his last appearance against Maritimo], I would like him to stay," Silas told reporters.
"Right now I don't know if he will stay or not, but I would like to count on him at least until the end of the season.
"Bruno Fernandes is a different player, he sees things that no one sees. Being further back and seeing these movements, the defence begins to decline.
"Any team that had Bruno Fernandes in Portugal would suffer if they lost him. If that happens we will have to look for solutions."
Fernandes, who has also been linked with Tottenham and Real Madrid in the past, has scored 15 goals in all competitions for Sporting this season.
The 25-year-old midfielder netted 31 goals last term, including 20 in the Primeira Liga.
Prior to his breakthrough with Sporting, the Portuguese star featured in Serie A for the likes of Udinese and Sampdoria, spending three seasons with the former.
He scored 11 goals in 95 total appearances for Udinese while adding five goals during his loan spell with Sampdoria.
United, meanwhile, currently sit fifth in the Premier League and face Wolves at Old Trafford on Saturday.
Prior to that, the Red Devils, who are fresh off a 6-0 FA Cup demolition of Tranmere Rovers, will face rivals Manchester City in the second leg of their Carabao Cup semi-final.
