West Ham look firmly in control here as they play out the final minutes.

They really ought to be three goals up now with Lucas Paqueta unable to beat the home goalkeeper in the final minute of normal time.

All over in Portugal as Arsenal settle for a draw. A decent game overall and well-balanced. Plenty of chances too.

Bukayo Saka cuts inside but it's straight at the goalkeeper again.

Mikel Arteta is urging his players to keep moving as they try to find an opening in the dying minutes. Ben White is lagging behind a little when Sporting regain possession and Arteta screams at him to get back. Tired legs now!

Fatawau Issahaku runs straight at Takehiro Tomiyasu but the Arsenal full-back does well and wins a free-kick in his own half.

Fabio Vieira can't get past Diomande in the box, then Bukayo Saka cuts inside and shoots straight at the goalkeeper from long range.

Sporting take a few seconds to make another change as Marcus Edwards is replaced by Fatawau Issahaku, another teenager.

We're getting closer to full-time. Any late drama from Arsenal again? They will surely be content taking a draw back to the Emirates though.

Takehiro Tomiyasu gets back well to block the run of Marcus Edwards. Sporting want a free-kick but don't get one, then St Juste comes in late on Tomiyasu.

Gabriel is put under pressure by Youssef Chermiti, who receives a cheer from the Sporting fans.

The hosts are pushing for a winner.

Almost. Fabio Vieira makes the run but Gabriel's lofty pass just skips past him and through to goalkeeper Adan.

Ousmane Diomande drags a shot just wide for Sporting after St Juste's initial effort is blocked by William Saliba.

This has all gone a little flat since those West Ham subs. Still David Moyes will be delighted if his team travel back to England with a two-goal lead.

Emile Smith Rowe's free-kick is curled in towards Takehiro Tomiyasu but he's penalised for a shove in the box.

A roar goes up by the home fans as Sporting immediately look to go on the attack.

Goalscorer Paulinho is off but Sporting have exciting teenager Youssef Chermiti coming on.

Someone for Arsenal to be wary of.

The flag is up as Gabriel Martinelli slides it through to Granit Xhaka. He pulls it back for Fabio Vieira but the whistle has already gone.

Thomas Partey makes his presence known immediately, kicking out late on St Juste as he tries to poke the ball away.

Manchester United officials have begun a round of presentations to potential investors.

The leading candidates, Sir Jim Ratcliffe and Sheikh Jassim, are due to send representatives to Manchester next week.

However, others, who are either offering to fund any purchase of United or redevelopment of Old Trafford or the club's Carrington training ground, are first in line.

It is understood there will be potential investors at tonight's game, potentially from the Elliott Investment Management group, who formerly owned AC Milan and are willing to provide funding around United rather than buy into the club itself.

Francisco Trincao is replaced by Nuno Santos for Sporting.

Thomas Partey, Emile-Smith Rowe and Gabriel are on for Arsenal. Off goes debutant Jakub Kiwior, Jorginho and Reiss Nelson.

Gabriel Martinelli picks out Reiss Nelson on the edge of the box but he fires it way over.

Bukayo Saka has been fairly quiet. He tries to link-up on the right, before cutting inside.

Mikel Arteta is preparing more changes in the dugout.
