Manchester United are set to increase security around executive vice-chairman Ed Woodward, amid fears that frustrated fans could target him.
In January, Woodward’s Cheshire home was attacked by a group of around 20 thugs, throwing flares and a smoke bomb during the attack.
The attack was carried out by so-called fans who had become increasingly angry at the the club’s transfer activity in that window.
United have been criticised again this summer, with many believing they have failed to match the ambition of their top-six rivals.
With days to go before the deadline, United have confirmed the signing of one senior player in the shape of Donny van de Beek from Ajax.
Many fans had expected United to land Ole Gunnar Solskjaer's top target Jadon Sancho, but Borussia Dortmund’s £108million valuation has blocked any potential move.

They are expected to seal a deal that will see former PSG striker Edinson Cavani move to Old Trafford, but that doesn’t look as if it will appease an increasingly disgruntled fanbase.
Mirror Sport report that since the attack on his Cheshire home, security has been increased, but that will be ramped up even further in the final hours of the window.
Woodward and his family were not at the home when it was attacked in January, but there are still some concerns about similar disturbances on Monday night.
The United chief warned supporters back in April that in the midst of the corona virus pandemic, it would not be “business as usual” in the transfer market.
He said: "Nobody should be under any illusions about the scale of challenge facing everyone in football and it may not be business as usual for any clubs, including ourselves, in the transfer market this summer.
"As ever our priority is the success of team, but we need visibility of the impact across the whole industry, including timings of the transfer window, and the wider financial picture, before we can talk about a return to normality."
