Man United's £40m 'mistake' has never looked like a better bit of business

United were by no means anywhere near their best, but they dug in when they needed to, produced the game's standout bit of quality and came up against a Chelsea side whose blunt attack misfired once again.

Matheus Cunha's classy finish shortly before half-time ensured those travelling fans went home with smiles on their faces. But the truth is the arduous trip to west London had been made worthwhile long before Cunha expertly guided his winning goal beyond Robert Sanchez.

The previous meeting between the two sides back in September marked the return of Alejandro Garnacho to Old Trafford. The Argentine had burnt his bridges at United a few months prior with an unceremonious exit, and if the reception he received at Stamford Bridge on Saturday night is anything to go by, he'll have been glad the extent of his evening's work at Old Trafford earlier in the season didn't extend beyond a watching brief from the bench.

The travelling United fans needed no encouragement to remind Garnacho of their feelings towards him. When the Chelsea forward lost out in a tussle with Diogo Dalot before being tossed to the floor in front of the away section, the cheers that followed were only marginally quieter than the ones that greeted Cunha's goal.

When United agreed to sell Garnacho to Chelsea for £40million, some believed United were making a big mistake. Not necessarily because they were wrong to sell him - his behaviour prior to his exit was in no way acceptable - but more so because the fee seemed so low.

Despite that £40million representing the largest fee United had received for an academy graduate, the callow winger clearly had bags of potential and was nowhere near the end product. Seven months on from his exit and you'd be hard pushed to find a Chelsea fan who still believes it was money well spent.

Recent reports have claimed Chelsea are already willing to part ways with Garnacho after a return of just one league goal in 22 outings for the Blues so far. While Garnacho's talent was never in doubt, his attitude was, and it's difficult to see him thriving at a club who seem to be in a constant state of transition and have an inexperienced playing squad led by an equally inexperienced manager.

Garnacho was one of the worst performers on the pitch on Saturday night. Dalot had his number in their duel on the United right and Garnacho was at fault for United's winning goal, failing to stop Bruno Fernandes as he teed up Cunha for the winner.

Chelsea supporters couldn't believe their club had managed to sign a player with such potential for £40m last summer. It's the United fans who are laughing now.
