Manchester United have made a frightening start to the season on all fronts.
They are joint top of the Premier League with rivals Manchester City, having won six of their first seven games, thanks largely to the brilliant form of Romelu Lukaku, who has seven goals in as many matches.
They also qualified for round four of the Carabao Cup with a 4-1 win against Burton Albion, and blitzed Basel and CSKA Moscow in their Champions League group, making them heavy favourites to qualify as winners.
They've even been without Paul Pogba for the last month, as he injured his hamstring in the victory against Basel at Old Trafford, but Marouane Fellaini has stepped in capably, scoring two as United beat Crystal Palace 4-0.
Despite their form, they are still being linked with potential signings, even in attacking areas where they have such prowess.
As one of the longest-running transfer sagas of the summer, it is no surprise to see the Red Devils continuing to be linked with Inter Milan winger Ivan Perisic.
The Croatian was one of Mourinho's top targets during the transfer window, but the club refused to match Inter's asking price for the former Wolfsburg man.
However, Gazetto dello Sport are reporting that that Perisic has a release clause in the new contract that he signed, which kicks in next summer, meaning teams will be able to buy him for around £54m.
The stumbling block is that Perisic will be 29 next summer, and such a fee would be very excessive for someone of that age, with potentially only three years left at his peak.
It is thought that the new contract included an 'anti-Manchester United clause', which would stop them from buying him in January, guaranteeing the Milan club get a full season out of him.
Perisic has started the season in good form for Inter, with three goals in seven appearances, as Luciano Spalletti's men find themselves third in Serie A.
If United did decide to go back in for the Croatian, it would add to their already impressive ranks on the wing.
Anthony Martial has barely started a game in the league for the Red Devils, and as a result missed out on France's squad for their international fixtures.
Marcus Rashford and Henrikh Mkhitaryan have been preferred, though both have chipped in with goals and assists this term, with Rashford getting two last weekend.
