The West Ham boss has been reflecting on the club's protracted contract talks with the defender.
West Ham United coach Sam Allardyce has expressed his frustration over the prolonged discussions the club held with Winston Reid before the defender extended his contract at Upton Park, according to the Daily Mail.
Reid recently signed a new deal with the Hammers but not without extended negotiations with the east London club.
And, although he says all parties are delighted with the eventual contract renewal, West Ham boss Allardyce has expressed his frustration by admitting talks were the 'longest ever.'
Reid, 26, is one of West Ham's star performers and leaders in defence - and Allardyce is hopeful thrashing out a deal with the New Zealander for a period of over a year will prove worth it.
"It was the longest negotiation ever," he told reporters.
"It's been a long, hard negotiation for him. It's been well into more than a year of trying to come to an agreement in terms of the contract. Now the contract is secured for a period of time that takes Winston along and hopefully the club along to better things."
West Ham face Arsenal this weekend in a key Premier League clash when it comes to ensuring their campaign does not peter out - the Hammers have slipped to 10th in the standings after spending large portions of the season in fourth and fifth place.
The east London side will have to cope without Reid on this occasion, though, as the 26-year-old is out of contention for the Arsenal clash with a hamstring injury.
