Anthony Martial and Marcus Rashford have been two of Manchester United's standout performers this season - but fans have barely seen them on the pitch together.The young forwards have been made to scrap for the left-wing position following the summer arrival of Belgian striker Romelu Lukaku.Martial, 21, came off the bench to score the winner in Saturday's narrow 1-0 win over Tottenham in the Premier League.“Sometimes he [Martial] starts the match and his contribution is good, maybe he’s not scoring but he’s playing very well,” Jose Mourinho told reporters after extending his incredible unbeaten home record to 36 games.He continued, “Today there was two strikers playing together against three of the top defenders in Europe. Their work was amazing, then Martial scores with a bad shot and a bad shot sometimes can be a beautiful one."The young Frenchman took his tally to the season for six whilst Rashford has already bagged seven in all competitions.Despite their impressive start to the 2017/18 campaign, their Portuguese manager is yet to name the duo in the same starting XI in the English top flight.

On Monday afternoon, Mourinho was asked about their lack of playing time together whilst speaking to the press ahead of Manchester United's Champions League fixture against Benfica.

The former Chelsea coach, who will face his former club at the weekend, insisted that Martial and Rashford can play together.

Despite that, he has to keep the likes of Lukaku, Mkhitaryan, Lingard and Mata happy and Mourinho noted that it's very difficult to fit both young forwards into the first XI for that reason.

"We played Marcus and Anthony together in Swansea one week ago," Mourinho told reporters. "So yes, they can play together – that’s no problem.

"What you can’t do is play with 12 and we can’t play with everybody at the same time.

"Nobody here thinks about any other match than Benfica. Nobody here thinks about Chelsea. It’s Benfica, Champions League and just Benfica."

The Red Devils have an 100% record in the Champions League thus far and a win over Benfica on Tuesday night could secure their spot in the knockout phase.
