In July 2017, David Moyes resigned as Sunderland manager less than one year after replacing Sam Allardyce.

The former Manchester United boss failed miserably in his bid to keep the Black Cats in the Premier League.

Sunderland finished bottom of the table with 24 points, having won only six games.

The football was drab and draped in defeat - but the 13 signings Moyes made certainly didn't help his cause.

In retrospect, it's no wonder a second successive relegation followed to League One.

Moyes's transfer business was absolutely horrendous.

Three of the 13 players he signed have been sacked for unprofessional behaviour and eight others have departed too.

The 13 unforgivable signings

Didier Ndong - Lorient, £13.6m

Sunderland's club record signing went AWOL after they relegated from the Championship last season.

Ndong, 24, was sacked on Monday and his career at the top level could be over after Sunderland threatened to take legal action to recoup the midfielder’s value should he join another club.

Papy Djilobodji - Chelsea, £8m

The Senegalese defender was sacked by Sunderland earlier in September after also failing to show up for pre-season training.

Djilobodji only made 24 appearances for the Black Cats, playing a starring role in their horrendous 2016/17 Premier League campaign.

Adnan Januzaj - Manchester United, loan

Big things were expected of the Belgian winger when he joined on a season-long loan deal from Old Trafford.

However, he struggled to make much of an impact at the Wearside club - failing to register a single goal in 25 Premier League appearances - and was sold by Man United at the end of the season.

Paddy McNair - Manchester United, £5m

McNair made a decent start at the Stadium of Light but ruptured his ACL three months after joining.

He was sold to Middlesbrough for £5.5m in 2018.

Donald Love - Manchester United, £1m

One of only two of Moyes's signings still at the club.

Love has struggled to become a first-team regular, making only 11 appearances in the Championship last season.

Steven Pienaar - Everton, free agent

Moyes signed the 34-year-old South African midfielder on a one-year deal after he was released by Everton.

However, the years had caught up with him and he retired from professional football six months after his uninspiring spell at Sunderland.

Jason Denayer - Manchester City, loan

The highly-rated Belgian international was often fielded in midfield instead of his natural position as a defender.

Failed to convince his bosses at Man City and was eventually sold to Lyon in 2018.

Javier Manquillo - Atlético Madrid, loan

The full-back endured a pretty disastrous campaign at Sunderland before completing a permanent transfer to Newcastle.

He made 20 Premier League appearances for the Black Cats, winning just twice.

Victor Anichebe - free agent

The former Everton striker was released at the end of his one year-deal after netting three times in 18 Premier League appearances.

Anichebe joined Beijing Enterprises in June 2017 but is currently a free agent after a disappointing spell in China.

Mika - Boavista, free

The first choice Boavista goalkeeper found himself firmly behind Jordan Pickford and Vito Mannone in the pecking order.

He never played for Sunderland's first team and his contract was terminated in January 2018.

Darron Gibson - Everton, £2.5m

Once a Man United player, Gibson disgraced himself during his time in the north-east.

In March 2018, the 30-year-old midfielder was sacked by Sunderland two weeks after being charged with drink driving.

Bryan Oviedo - Everton, £2m

The Costa Rican full-back suffered with injury problems in his debut season at Sunderland but has been a regular in the first-team in the Championship and now League One.

Incredibly, Oviedo was probably Moyes's best signing. However, the bar is really, really low.

Joleon Lescott - free agent

Terrible signing.

The veteran defender made two Premier League appearances and retired at the end of the 2016/17 season.
