Norwich City forward Nelson Oliveira has been the subject of interest from the likes of Derby County, Wolverhampton Wanderers, Fulham and Swansea City in the #January transfer window.

The 26-year-old joined Norwich full-time in 2016 from Benfica, after a loan spell at Nottingham Forest. He has scored 19 goals in both league and cup for the Canaries. He recently returned to Portugal's national team after nearly two years absent and scored a goal in Portugal's 5-1 victory over the Faroe Islands in their World Cup qualification match back in August.

Oliveira's current contract with Norwich lasts until 2020.

Why do the interested clubs want him?

Derby County is believed to have ignited the other club's interest in Nelson Oliveira by offering him a transfer worth £8 million. The Rams are currently second in the Championship table with nine points between them and the leaders Wolverhampton Wanderers.

The Wolves have been known to want him as well, as they aim to boost their squad vying for promotion to the Premier League for the first time since they were relegated in the 2011/12 season. They are on the lookout for players who have potential to play in the top-flight of English football.

Fulham is another promotion-chasing side to have shown interest in the Portuguese international as Slavisa Jokanovic looks to add more attackers to Craven Cottage in order to increase goals.

Swansea City of the Premier League is also keen to snap him up in order to save their season. Oliveira spent half of 2015 for the Welsh side on loan when Garry Monk was the manager at the Liberty Stadium. Swansea was rumoured to be after Oliveira in the August transfer window but ultimately didn't get him.

What we know about Nelson Oliveira so far

Nelson Oliveira started his football career in his native Portugal with Santa Maria as a junior player in 1999 and played for other clubs as a youth before joining Benfica at aged 15. He made his senior debut for the Primeira Liga club in 2009 but didn't get much time on the pitch and only scored three goals.

Ironically, Oliveira has shown more talent when loaned to other clubs rather than at Benfica, both at home and abroad. He was first loaned to Rio Ave and subsequently Pacos Ferreira, but overseas clubs took an interest in him and he had loan spells for Deportivo La Coruna and Rennes, for a year each.

As mentioned earlier, Swansea City was his first venture into English football. He made 11 appearances for the Swans in the final part of the 2014/15 season, mostly from the substitutes bench. His only goal was a header from a corner kick in an away match against Newcastle United.

Oliveira joined Nottingham Forest on loan for the following season and showed Benfica what they were missing by scoring nine times in 29 appearances in all competitions.

He was bought by Norwich City for an undisclosed fee in August 2016 and has even played twice for the Under 23 side in the Checkatrade Trophy and netted in three goals.
