Marcus Bettinelli hails from Camberwell, South London, and began his career in the capital with Fulham.

He progressed through the Fulham Academy, where father Vic Bettinelli is a goalkeeping coach. 

Now 28, Marcus’ first taste of first team experience was with Dartford in the Conference Premier, making a total of 42 appearances while on loan at the club in the 2012/13 season.

The following campaign he was loaned to League Two Accrington Stanley, where he played his first games in the League Cup and the Football League and was a staple under former Boro coach James Beattie. 

Marcus made his long-awaited Fulham bow in August 2014, keeping a clean sheet in a 1-0 League Cup victory away to west London rivals Brentford.

Four days later he made his league debut for the the Whites, a 1-1 draw with Cardiff City at Craven Cottage.

Fulham’s number one throughout the 2014/15 season, Marcus lost his starting spot in the following two seasons, first to due to a long-term knee injury with former Boro man Andy Lonergan stepping in, then to David Button.

The keeper did win back the gloves from Button for the closing months of the 2016/17 season, playing a big part in the club’s unlikely top six charge and featuring in the Play-Off semi-finals against Reading.

Marcus had done enough to convince manager Slavisa Jokanovic he was the man for the job, and was a regular in Fulham’s revival during the second half of the 2017/18 campaign. The Cottagers reached the Play-Offs again, this time winning at Wembley against Aston Villa.

Marcus made his Premier League debut with Fulham on the opening day of the 2018/19 campaign, a 4-2 win over Burnley, and made six more top flight appearances that season as Fulham failed to escape the drop. 

The glovesman was restored to the Fulham starting line-up for the start of last season, and made 14 appearances until early November.

The penultimate of those was a goalless draw with Boro at the Riverside in October, in which Marcus came on to replace the red-carded Marek Rodak - the man who would go on to claim Fulham’s number one spot that season as they once again proved triumphant in the Play-Offs.

Marcus was called up for England’s Under-21s for the first time in November 2014, and made his debut for the Young Lions against the Czech Republic the following March. 

In September 2018, he was called up to the England senior squad by Gareth Southgate for matches against Spain and Switzerland.
