Patrick Vieira believes Arsenal must make four key signings this summer if they are to try and challenge Manchester City for the Premier League title again next season.
The Gunners were beaten 3-0 by Brighton & Hove Albion at the Emirates Stadium, effectively handing City the trophy. Pep Guardiola's side had beaten Everton 3-0 earlier in the day to move four points clear at the top.
Arsenal's defeat means the gap is seven with City having played a game fewer. Guardiola could watch his team win the league next weekend against Chelsea if they match Arsenal's result against Nottingham Forest.
