Nottingham Forest and Aston Villa went toe-to-toe in an all-English UEFA Europa League semi-final on Thursday evening, leaving it all to play for in the second leg in Birmingham next week.

Vitor Pereira's Forest side will take a 1-0 lead into that game, after Chris Wood thundered a penalty in with 19 minutes left on the clock.

Forest and Villa had already played each other twice in the league this season (and because of the way the fixtures fell, both games were this year: in January and earlier in April).

The game in January saw Villa win 3-1 at home, while the reverse fixture ended in a 1-1 draw.

The two sides, who are just 43 miles/69 kilometres apart, are steeped in European history.

Forest famously won back-to-back European Cups in 1978/1979 and 1979/1980, and Aston Villa lifted their sole 'Big Ears' trophy in 1981/1982.

Unai Emery's side came into this game off the back of some shaky form in the league.

After the draw against Forest, they left it late in a 4-3 win against Sunderland, before losing to Fulham on Saturday, sending them into fifth place (although they are still eight points above sixth).

They did, however, convincingly beat Bologna to reach this game, winning 7-1 on aggregate.

Forest, on the other hand, were in excellent form.

Having knocked out FC Porto 2-1 on aggregate, they'd also gone five unbeaten in the league to give them some distance to the final relegation place.

Their 5-0 win away at the Stadium of Light in the game before this one was a shock to many and allowed the Reds to place more focus on Europe, now that relegation seems unlikely.

This tactical analysis looks at a game that was a cagey affair, with both teams not looking to take a lot of risk before the second leg.

It will focus on how the shape of both teams dictated the play, the individual performances that stood out and the penalty incident that made all the difference.

Nottingham Forest Lineup Vs Aston Villa

Pereira was forced into two of the three changes he made from the win against Sunderland last week as he kept the 4-4-2 shape that had worked so well in the North-East.

As usual in the Europa League, Stefan Ortega came in for Matz Sels in goal.

Ola Aina and Neco Williams kept their places at right and left-back, while Morato came in alongside Nikola Milenković as there were injuries to Murillo and Jair Cunha.

Omari Hutchinson started wide on the right, with captain Morgan Gibbs-White on the opposite flank.

Nicolás Domínguez came in for the injured Ibrahim Sangaré to partner Elliott Anderson (who had missed the home tie against Porto due to personal circumstances).

The Portuguese manager then kept the duo of Chris Wood and Igor Jesus as a two-man attack.

His options from the bench were extremely limited, with an injury list that included Dan Ndoye and Callum Hudson-Odoi.

He only made two substitutions throughout the game, with Zach Abbott replacing Aina on 75' due to injury and Ryan Yates replacing Jesus to see out the game in injury time.

Emery made just one change from the defeat at Craven Cottage, with Lamare Bogarde losing his place to Amadou Onana in midfield.

It's no surprise that the Basque manager stuck with his trusted 4-2-3-1, which has become a staple of the Midlands side since he took over.

Emi Martínez started in goal, with a defensive four of Matty Cash, Ezri Konsa, Pau Torres and Lucas Digne ahead of him.

The midfield was a Belgian double pivot of Onana and Youri Tielemans.

The attacking unit had Emiliano Buendía on the left, Morgan Rogers through the middle and John McGinn on the right.

Ollie Watkins led the line in his 272nd game for Villa.

Emery had more to call from on the bench and made four changes.

Bogarde replaced an injured Onana on 55'.

He then made a triple change with less than fifteen minutes to go, bringing on Douglas Luiz (who had spent the first half of the season on loan at Forest), Ian Maatsen and Jadon Sancho for Digne, Buendía and McGinn.

Nottingham Forest Vs Aston Villa: Battle Of The 4-4-2

The first half was an extremely tight game, as both teams tried to feel each other out in true European semi-final tradition (Paris Saint-Germain Vs Bayern Munich excluded).

Aston Villa started the quicker of the two sides, and created a half-chance from Rogers within the first two minutes.

This goal kick, which started the move, gives us a good glimpse of Villa's build-up shape and how Forest looked to contain them.

The home side used Wood to sit with the two deep midfielders, while wingers Hutchinson and Gibbs-White tucked inside to squeeze the space, and Jesus was the free man, allowed to hassle the centre-backs and goalkeeper.

Villa, on the other hand, pushed their full-backs extremely wide (so much so they aren't in shot) and tried to entice Forest to press before rotating the ball out to them.

In this instance, it works.

Villa get the ball out to Digne, and Forest's high press is evident, with Aina and Hutchinson immediately pressuring the Frenchman.

In this instance, Digne releases long, and a flick-on finds Watkins making a run beyond the defender.

As the half went on, Forest got more luck.
