An Everton scout was in attendance for Friday's Primeira Liga clash between FC Porto and Sporting Lisbon, according to Portuguese newspaper O Jogo (via Sport Witness).

The lowdown

Paulinho and Nuno Santos fired Sporting into a two-goal lead within 35 minutes, but Fabio Vieira and Mehdi Taremi responded to preserve Porto's unbeaten record and indeed the six-point gap between the two teams.

The game also saw five red cards, with Sebastian Coates dismissed in the second half and four more players - Joao Palhinha, Bruno Tabata, Agustin Marchasin and Pepe - seeing red after the final whistle as a fight broke out.

Planning will be underway for Frank Lampard's first full transfer window at Everton, with the 43-year-old only officially appointed on deadline day last month.

The latest

A report from O Jogo on Saturday (via Sport Witness) revealed that an Everton official was watching on at the Estadio do Dragao.

They weren't the only Premier League club assessing the talent on show, with a Newcastle scout also on the scene.

The verdict

Who might Everton have been watching on Friday? One likely candidate would be Sporting midfielder Matheus Nunes.

O Jogo reported last summer that the Toffees were interested in the Brazilian, while Record claimed that a deal was 'very close' at one point and raised the possibility that it could happen at a later date. The player himself admitted that the interest from Merseyside was genuine.

Nunes produced a decent showing on the night, completing four of his five dribbles, winning the majority of his 25 duels and making three tackles (via SofaScore).

The 23-year-old, who is valued at £19.8m by Transfermarkt and was described as a 'quality box-to-box midfielder' by talent scout Jacek Kulig, may be one for Blues fans to keep an eye on, particularly with the eminent possibility that Goodison Park scouts have noticed his talents.
