Sunderland fans could justifiably feel sick every time that Oli McBurnie scores for Barnsley.
The young Scottish striker bagged his sixth goal in eight Championship games for the Tykes last night and he continues to look like an outstanding signing, having joined on loan from Swansea in January.
Sadly for Sunderland, it was they who looked most likely to sign the 21-year-old in January and The Chronicle reported that Chris Coleman was 'closing in' on the youngster at one point.
However, a move to the Stadium of Light never materialised and the Black Cats wound up signing Ashley Fletcher on loan.
But the Middlesbrough-owned striker hasn't scored in seven Championship games for relegation-threatened Sunderland you must wonder how less precarious their situation would be had Coleman got McBurnie.
Worse yet, McBurnie is actually pushing Coleman's side closer to League One, given that his goal on Tuesday led to a 1-1 draw with Norwich City and that point means that bottom-of-the-table Sunderland are now five adrift of safety.
Fans of the Wearside club will undoubtedly reflect on the multitude of 'what if' moments which have shaped their disastrous season, but 'what if they signed McBurnie instead of Fletcher' might be the most agonising question of all.
