Sunderland have had plenty of high-profile transfer blunders in recent years, many of which contributed to their catastrophic slump down the divisions.

In an attempt to decelerate their fall, the hierarchy made numerous added mistakes which further compounded the mess they found themselves in.

For a club that had just been relegated to League One, spending £4m on Will Grigg was a move somewhat well-received due to his popularity across the country, but provoked wariness.

Every football fan across the nation knew his classic song, and he was coming off the back of scoring 19 the season before for Wigan Athletic in the same league.

He was also handed a handsome wage of £6k-per-week, which spread out across his 173 weeks at the club adds an extra £1m to his total cost to the club.

Scoring four in the second half of the season for the Black Cats was a respectable but ultimately underwhelming return, and he would only go on to play 62 times for the club in total.

A return of just eight goals across this period marks a huge disappointment for the man they hoped would fire them straight back to the Championship.

In the season where they eventually did manage to earn promotion, Grigg was out on one of his many loans. There was hope they might spark him into action, to eventually gather some return on their sizable investment. Unsurprisingly, this never came to occur.

Stephen Elliot showed a wariness with regard to his career on Wearside early on, when he took to Twitter to claim: “Grigg looks like he is a million miles away. So worrying with playoffs coming."

What makes it all the more frustrating is the fact that he has scored goals for plenty of other clubs, with 65 for the Latics and 33 goals in just 79 for MK Dons.

He also left on a free, compounding the terrible deal which further financially hamstrung the club.

Grigg drained Sunderland during his time and adds to a long list of awful transfer decisions made in recent years.
