Mitrovic failed to get on the scoresheet against the Hammers, but he still impressed with his link-up play.
The Serbian worked tirelessly up front, and Jenas highlighted the powerful striker’s importance in Newcastle’s 2-1 victory over Slaven Bilic’s side after the match.
“Mitrovic was another player [who played well],” Jenas said. “In the second half West Ham did step it up, putting Newcastle under a lot of pressure.
“Mitrovic defused that by holding the ball up very well, coming back and trying to get his team up the pitch.
“You can’t underestimate when you are under pressure, [the difference] your centre forward doing this makes.
“It was just a shame he couldn’t put the icing on the cake.”
Mitrovic had a number of chances to score to round off his promising display, but he failed to take any of his chances.
That has rather been the tale of the 21-year-old’s time at St. James’ Park so far, as he has struggled to hit the back of the net with any frequency.
Mitrovic has only four goals so far this season, and his failure to be a potent scorer could force Newcastle back into the market in January.
