Football can be quite the cruel sport at times, even when nothing is happening on the pitch.
For every club there's likely to be a handful of players whom they could have signed, but didn't and are now watching them put in world-class performance after world-class performance for another side.
Scouts will tell you that it happens all the time. There's always that one recommendation that clubs pay little attention to, only to regret it years down the line.
Such is the case with Pierre-Emerick Aubameyang.
The Gabonese striker has been lighting it up in the Bundesliga with Borussia Dortmund for a few years now and Stuart White, a former West Brom scout, has revealed he could have signed for the Baggies in 2011 upon his recommendation, after watching him play for French side Saint-Etienne.
White, who spent 15 years working for the Baggies between 2000-2015, said as much, via planetfootball.
“I had been to Dijon on a Friday night to watch one player in particular, a centre forward who didn’t impress me at all,” White said.
“My ‘bonus game’ before flying home on the Sunday, was Auxerre v Saint-Etienne on the Saturday night.
“Saint-Etienne drew the game 2-2, but Aubameyang and Emmanuel Riviere were tremendous as a pair.
“I came back raving about Aubameyang, and as luck would have it his agent called me the following week, probably because he’d got to know that I had been at the game.
“He was obviously calling many clubs, but the lad was then a Milan player on loan at Saint-Etienne and he was interested in coming to England.
“The outline deal was explained to me and it was clear that he was going to be affordable so I recommended that we pursued it."
“On the back of my shout, a few more of our scouts went out to watch him a week or two later and he scored an early goal against Sochaux in a 2-1 defeat but didn’t impress sufficiently on the night, which can happen.
“He then went back to Saint-Etienne, scored 21 in 45 and was subsequently sold to Dortmund for 13million euros. He would have been a free loan to us with a 2million euros fee tied into the deal had we taken him.
“I have to stress, every scout in the land will have a similar story and some may even have the exact same one, it happens."
